a) I think I have a (a bit under?)average IQ but I have no idea. I have done ok in school but I have always needed more time, I am pretty slow. My chess ELO is between 1350-1450 but I learned the moves when I was 8 and started playing casually everyday for 3 years now.

b) 1 cigarette a day or none depending on the period. But rises significantly when drinking and partying

c) I am in good health and overheating is generally a problem that arises sooner that breath issues when exercising Almost never sick. I get between 0 to 2 illnesses a year depending on how much I find myself with lots of people in a room

d) Hard to tell. I feel smarter than a lot of people but I only feel it's because I am much more curious. On the other hand, I am pretty slow. I have self-confidence/laziness issues that prevent me to actually look for a dev job.

Started smoking at 19, first occasionally, then regularly, now occasionally again What do you say, doc ?
