I have insane pattern recognition (it doesn't serve a great deal of purpose in real life though, other than normal decent pattern recognition might). Knowing what buzz words to use to get my point across to certain people has been good though (teachers, various medics, landlords etc).
I've had my poetry published when I was a teenager. My English teacher told me to send it to a few publishing houses and one of them accepted it. I get about a tenner a year in royalties
I'm really fucking good at cpr, which is actually pretty useful in my line of work, as is not panicking when the shit hits the fan, which I'm also very good at. I just do all my hyperventilating and crying once the crisis is over.
I'm also left handed, we're one in ten, we're really not that rare. I also have red hair and orange eyes though, so genetically, pretty rare. I'm type of neg blood too so universal donor which is pretty cool, but I'm very short (4ft10) so not quite heavy enough to donate blood when I'm at a healthy weight.
I decided to quit smoking one day about 13 years ago and just.. Stopped. No smoking cessation sessions, no nicorette. Just stopped completely one day. Didn't even finish the last couple I had in my pack I gave them away. Haven't had a cigarette /vape /nicotine patch since.
