People who can’t bring themselves to believe anyone else has a food allergy. I once had a lady at a Bed and Breakfast slip cranberries into my food to “prove” to everyone I wasn;t really allergic. When I dashed upstairs for my epi-pen (as my throat constricted) her husband came up to yell at me for upsetting her.
It may TECHNICALLY true, but I am still doubting it. I do believe OTHERS put this in your mind as you say (and that was my initial thought as well).
Think about it.
How much do you think your shoes compress when you stand on them? With all that spongey rubber and foam and shoes and socks and what not.
How much do you think something like concrete or asphalt compresses when you stand on them? I’ve seen something like a quarter million pounds sitting on asphalt and its only “sunk” a “tiny” amount.
Squeeze the soles of your shoes between your fingers. Do the same with a chunk of concrete and//or asphalt.
Of course OTHERS put this in my mind. Namely, someone with an MD and years of specialized training.
I’m sure your explanation makes sense to you, but honestly, how dumb would have to be to blow off my doctor over one random person’s opinion from a message board?
I personally know a case where an MD who told a guy with an heart condition that a newly formed large blind spot in his eye was no big deal.
Any tard with a lick of sense would tell you that it happened because a blood clot moved into his retina.
Three weeks later, after visiting a REAL doctor, said guy had a desperately needed heart valve replacement.
I am telling you that the shoes you wear compress and expand WAY more than either concrete or asphalt.
Dont trust any crap you hear off the internet (including me). Also dont trust anything any one MD tells you either.
There was a guy in the park the other day wearing a T-shirt that read: “A child is more than a test score”. At first I thought, “I can get on board with that.” He was chatting with his neighbor, an Asian woman, about the new school her son is attending. Soon, another boy and his dad walked by, and we noticed that the kid had, not quite a mullet, but a “tail”. The woman made an admiring comment about the child’s “queue”, like that of Chinese men. The dude in the T-shirt told her that in the U.S., that type of hairstyle is a symbol of “white trash”, and that her son did not need one. When I pressed him further, and asked if he had ever had a mullet in the 80’s, he replied, “I never sank that low,” and he got noticably agitated, sort of hopping from one foot to the other. When I teased him about any tattoos or piercings, he said that those are okay. I thought “Wow, he’s really threatened about something as temporary as hair, but tats and piercings are okay.”
I wondered, “Isn’t a child more than a haircut?”
I will walk on nearly any surface in 4 inch heels with no problem (albeit slow as hell), so I really don’t have a reason to jump in the middle of this, but I do find myself wondering…
Does it make a difference when it comes to running? Because I would assume the body would be crashing down with a much stronger force, then. Wouldn’t the asphalt have a bit more…give?
I’m kind of going to agree with billfish here, in that for walkers that aren’t grossly obese, concrete vs. asphalt isn’t going to make that much of a difference. For a consistent runner, though, it will. What will make a big difference is the type, quality and age of your walking shoes. Make sure your shoes aren’t so old that the foam is remaining compressed when you’re not wearing them (look for striations and when you find them toss them out, go get a new pair). Knee pain can also be attributed to overpronation, which good arch support can alleviate. If you haven’t been evaluated, you should be.
Finally, if your joints are bad enough to be irritated by walking, avoid paved paths/roads altogether and get yourself on a greenway or an easy trail. Grass and dirt generally has a lot more give than any pavement and that’s what our bodies were designed to walk on anyway.
Don’t doubt it. You’re wrong about this.
I’ll continue to run on asphalt instead of concrete when I have the option, because over the course of many years running many thousands of miles, my experience is in direct conflict with your assumption.
Seriously.
Dig up the numbers for modulus of elasticity for concrete, asphalt, rubber, foam, socks and human flesh. Do some calculations.
The harder stuff is a thousand times (off the top of my head) stiffer than the soft stuff (if not more).
As noted upthread, the shoes are THE important thing. They are the thing that does the vast majority of taking the shock/load (besides your body, which is what your just stuck with, so thats a constant).
Worrying about concrete vs ashpalt is like the dieter who drinks only diet drinks but pigs out at the buffet. Except in this case its more like the difference in a single sip of diet vs regular.
There may be a slight, mostly theorectical advantage to asphalt, but IMO it is greatly outweighed by the non zero and certainly bad consequences of getting your butt run over by a car. Or causing an accident.
The comment upthread reminded me that I get all judgy about people who feel they must post ridiculous minutae on their Facebook pages. I have a friend who’s constantly posting about doing his laundry or cleaning the house. Seriously, who gives a rat’s ass?
I also get somewhat judgmental about people who are on diets and must recount every damn thing they ate that day. Yes, lady who sits on the other side of my cube, I’m looking at you. Good on you that you’re working on losing some weight, but we’re at work! Do you really have nothing better to do than interrupt me to tell me what you’re eating?
I’m also judgmental about people who dress inappropriately. Look, it’s great that you’d like to stick it to “the Man” and show the corporate world that you don’t care what they think of you. Hear, hear! But keep in mind when you’re flapping your way into work in your flip-flops and your shirt artfully untucked to billow so elegantly over your stained khakis that you’re communicating something else, too: “Don’t bother to promote me. Even if my work is stellar, I don’t care what you or anyone else think of me. My efforts to be different are far more important to me than making a good impression on a client.”
Wasting people’s consumables.
A former friend would come over and say “How about some Scotch?” Then proceed to help himself to as much as he wanted. Every bloody time I’d straight out tell him that I didn’t want him touching my Scotch unless he was pouring me some, but every damned time he’d pour himself shot after shot without asking or pouring one for me. When I’d say something, he’d look confused and say “Oh, did you want some?” Yes, you dumbass, and I repeatedly told you not to drink my Scotch without me. YOU ARE NOT GETTING THE MESSAGE.
The same guy, when I used to smoke weed, would accidentally spill it on the floor, dump out half-full bowls into the ashtray, and torch the hell out of every bowl with the lighter, wasting a lot of it.
I used to bring in kleenex to work and leave them on my desk for anyone. Until I watched the idiot next to me regularly grab 4-5 at a time, blow his nose into them one handed, toss the bunch and reach for more. Excuse me?
Oh, and I don’t bring hand sanitizer to work anymore either, because of the people who would come by and help themselves to enough to coat their entire body, then walk away with most of it dripping on the floor as they rubbed their hands together.
I don’t need to dig up any numbers, because my empirical data tells me what I need to know. But you’re welcome to if you wish. If your argument is based on trying to keep runners off the road so we don’t get our butts run over or cause an accident, then I accept that as something you’re justified in feeling judgmental about, because it annoys me too. But because of when and where I run (early morning, in my quiet development where no cars are on the road at that hour), it doesn’t really apply to me.
I don’t think your analogy really works, though.
Um, wow. I feel for you. Did the former friend get told off by you one day or something? That would have been cool to watch. 
I can accept the French manicure, even on acrylic nails. My stepmother often had her nails done this way before it was trendy. They do have a clean look, but what I hate is the French pedicures. It just seems pointless to have a 0.5mm-wide sliver of white on the imaginary free edge of the pinkie toenail.
People who can’t be bothered to re-shelve volumes (e.g., of library encyclopedias) in the correct order. It’s not that much extra effort, jerk. It ensures the next person who wants it will have an easier time finding it. And if you were able to read the book in question, you have to be able to read the spines of the remaining volumes on the shelf to determine where the one you are holding belongs.
Runner (and engineer ;)). The concrete/asphalt difference is quantitatively minor, but still very significant when you consider the repetitive stress that your body absorbs over the thousands of steps in just a single running session. Simple test–whack asphalt with a hammer, and then concrete. Concrete returns almost all of the shock elastically which gets rung up into the handle and your forearm, while asphalt deadens the blow significantly. Even the age and grade of the asphalt makes a noticeable difference, new blacktop on a hot day is easy to run on. Worn and hardened is much worse, though still not as hard on the legs as concrete.
In a perfect world of perfectly fitting and worn shoes, yes they should mitigate the surface, but our feet and shoes in the real world do are not a 100% pure filter of shock from the surface.
I have a crappy car, but I disagree with you somewhat. If I were in field sales, I would have to have a much nicer car than the one I drive to accomplish my job.
Count me as one who loathes tats. Basically all of them, in fact. I’m really looking forward to school starting, because then I get to mock all my seniors who can’t wait to turn 18 so they can get a permanent reminder of a temporary feeling. I think anybody with tattoos who isn’t a sailor, Marine or Maori is lacking in judgment and not to be wholly trusted with anything important. It is painting with an enormously large brush, but I just think tats are so stoopid that the splashing about of pigment is warranted.
I have a problem with this, too.
Especially since I can’t afford to live in my own house. (Note: my membership was gifted.)
I get all nose-turn-uppy when I see bathroom windows in which people have stored their rusting cans of cleanser or other oogy cleaning supplies. Seriously, did they think that putting this stuff on very public display enhanced the look of their home or apartment? Put it under the damned sink already.
