No, this is a common misconception. A lizard, for example, can endure extremes of cold because it is cold blooded; its blood’s temperature will adapt to the ambient temperature and the lizard will not feel cold. A human is warm blooded; it’s blood has to be maintained at rought 98.6 degrees F. As the ambient temperature goes down, the body has to work harder to keep the blood at 98.6 and that is why warm blooded creatures, including man, feel colder.
Have you asked them?
Cold blooded animals love to bask in a warm spot. That seems to me to indicate they do feel cold, there just isn’t anything they can do about it.
I call my mother “Mothra.” People don’t get it, but it’s contagious. She’s even adopted it as her internet nickname.
I totally do this. I pick at my skin too, though I’ve managed to cut back since that’s more obvious and makes people ask me why I have tiny scabs on my arms.
I pace a lot. I don’t get how people can just stand in one place while nothing is happening. Sometimes I get up and walk around in the middle of meals because man, I’m just sitting here and eating. That’s boring! This is another thing I try not to do around other people because they ask me where I’m going and don’t seem to understand “I’m just walking”.
I talk to myself, as in I make up entire conversations with people. For instance, if I have to write a paper or something I will walk around and try to explain my main concepts to a pretend person. Or I talk in Russian to a pretend Russian because hell, I get no practice otherwise. I don’t talk out loud but I do move my lips, so there’s another thing I can’t do in public. I slip up sometimes though. I wonder how many times I’ve been the crazy lady :smack:
I move a lot. I have this personal goal to live in as many cool places in the U.S. as possible. My family thinks that I am ‘lost’ or ‘running away from something’. I am neither…there is nothing like the adventure of a road trip with my trusty side kick, MiAmor (my dog) to discover a new place. Love it! Pure freedom…
Hey…sounds like we have the same strategy…and possibly, the same job 
I largely think in words though not as utterly as you. I do hear in my mind many words that I read & all that I write; & see (in type) in my mind many words that I hear & all that I say. But I don’t tell people this, so no idea what they’d think.
…
What do I do that people don’t understand? …I read the SDMB.
Oh, I envy you. I shout at the walls, I talk in almost my conversational volume while walking by myself, I mutter quietly in tone without phoneme if trying to hold it in, & it can be bursting to get out. It’s painful.
I am a theatrical Production Electrician. In a nutshell: I plan and supervise the installation of lighting rigs for theatrical events, television, film, corporate events, trade shows, etc. Sometimes I am also the programmer.
It’s not a job or a life for everyone, jtsPimp, but I can’t really imagine living any other way.
hmmmm I see some trouble here. Gonna have to add Hostile Dialect to my list. <sigh> work work work… 
I fold small bits of refuse into neat squares. For instance, straw wrappers or empty sugar packets, candy wrappers and the like. It’s a trait I picked up from my dad.
I wave my arms around in front of me when I’m excited. If it’s a confined space, I wiggle my fingers together. It’s just a good way for me to channel nervous energy.
I am SO glad to hear I’m not the only one doing things like this. For me its my fingernails/cuticles, they look like they’ve been through a shredder.
I Ching
Nobody knows what the hell I’m doing when I throw three coins six times and write down a sequence of numbers. I’m not one of those “ask one question in a reverential manner and meditate on the answer” either. I tend to ask follow-up and clarifying questions.
Of course, now that I’m training to do support for a company that has a lot of i(product name) stuff, I joke that I’m working on their next product, the iChing. 
I chew paper, I’m not sure why, and I don’t do it as much as I used to, but I’m the only person I know who does this.
Neat freak is about all I’ve got. Can’t stand crumbs on the floor or counters.
Also obsessive with my car, no eating, limited drinking if you’ve proven you’re not a spiller. Nothing stays in my car except the essentials; cell phone, garage door opener, MP3 player, sunglasses. Any junk I’m carting around has to come out of the car when I get home. I do have a pickup truck that I’m not as picky about. At least the interior anyway.
