I might kill myself by then .
I'll probably be alone or with an adopted kid that I'll pick based on his/her intelligence.
I'll have a cat. I'll be a scientist doing research(hopefully) .
I'll still drink tea and suck lemons .
I'd like to be a member of the Science party , trying to make it more famous and appealing.
In case of WWIII I'll be a deserter ( I don't really care who's gonna win ) and if I'm lucky enough I'll move to Iceland forever.
Or perhaps be part of the UN if it still exists ( our future unique country ... hopefully if humanity makes it till that point ).
