Despite being a big guy, my blood pressure is normal or a bit low…almost any time it’s measured I get a question or comment from the nurse. Thanks, forbears!
I can cut a deck of cards one-handed, either hand.
Our parents were immigrants and unable to pay for college, but both my brother and I grew up not wanting for anything important, made it through grad school and did well. Thank you parents, and thank you land of opportunity!
I can’t come up with an exact analogy from my life, but I totally get that.
I live debt-free.
I do too but that is hardly unimportant, accidental or easy for most people to pull off.
Now, I don’t have numeric synesthesia at all, but I do see colors for days. Sunday is red. Monday is maroonish-brown. Tuesday and Saturday are silver-white. Wednesday, Thursday, and Friday are all the same shade of khaki. Even more weirdly, I envision the week not from left to right, but as sort of stretching out in front of me and bending to the left, for Pete’s sake. Don’t know why.
We should form a team. The original Trivial Pursuit was written for someone exactly my age, with precisely my level of cultural awareness and curiosity.
But why oh why do none of my talents translate to a marketable skill?
(“Hi, mom. Just wanted to let you know I’ve joined Apple as Vice President in charge of Drawing Teeny Tiny Maps of Mythical Places That Fit On a Postage Stamp. Oh, and Sir Jony Ive loves your nutmeg molasses cookies.”)
In addition to having great teeth despite only brushing once a day.
I can chip off bits of tartar the size of sesame seeds from the back of my front teeth. My dentists are always shocked that I can get that much tartar in 6 months.
I have never cheated on a test or grubbed a grade.
I’m really good at board games.
That is quite an achievement to be honest, I don’t think you’re missing out on anything. I only go there a few times a year and I admit the experience were not pleasant. This isn’t some upper middle class pretension either, it’s just weren’t pleasant to shop there for me.
This is my dream, one day… one day 
I make an awe-inspiring (and decongesting) chicken soup with matzoh balls.
I’ve edited/created entries for Wikipedia and later come across articles on the Internet that prove my edits were useful to someone.
I can bake a chocolate cheesecake that will curl your toes. Don’t tell anyone that baking cheesecake is dead-easy, much easier than almost any other desert.
I’ve never smoked a cigarette or pot. Despite living with a hippy wife. This is a streak I’m taking to my grave.
Whenever I get something from a high shelf or open a pickle jar with my bare hands, or lift a moderately heavy box for my wife, I feel super-manly. Yes, I’m an impossible badass at 5’10", and can lift 50 pounds without breaking a sweat. Worship me puny mortal females!
At my current job (since April 2015), I have yet to meet a cat I can’t pill. Coworkers and clients alike are amazed!
I can poop in 5 minutes or less (barring constipation or illness).
I have an amazing sense of direction and never get lost.
Ditto!

I can pick nits like… man, almost like I was a Doper! Yesterday I was reading the Environmental Report of my new employer and I found half a dozen typos 
Now if I could find a way to disengage that part of my brain…
I can drive anything on wheels, have a ridiculously accurate sense of direction, and can parallel park like a boss.
At 55 I have zero debt, not even a mortgage.
My wife and I have been together for 26 years; lots of people can boast about longevity in a relationship, but it’s still something I’m proud of.
I am literally awesome at picking literal nits. My daughter has caught head lice three times (once a year since she began school), and I am just so good at treating them. I channel my inner great ape, focus my Doper skills and just go completely OCD. Problem: solved. My girlfriends tell me about their struggles with delousing their own kids and I nod along, make sympathetic noises, but I secretly just want to step in, take over and treat that kid’s hair myself because I’ve got this. This is my niche, my oeuvre, my zone. Nitpicking. I didn’t pick nitpicking; nitpicking picked me.
I construct audio soundtracks out of people’s narratives of their own lives.
It’s your Secret Ninja Skill.
Mine is gift wrapping. My family can’t figure out how I can wrap such awesome presents, with every corner perfect and every seam just so, with the pattern matching and so on.
If I had been given a peek in the grab bag of Secret Ninja Skills, I might have chosen something related to guitar or throwing darts, but I got the Gift Wrap Skillz.
