"Forgetting your age is a real problem. The only people who remind me how old I am are my kids, and i often have to double check. I used to ask my parents how old they were and they always "cant remember" or said "21" and it confused me. I get it now."
If this post make you think of suicide, then you are the teacher audience and missed the point.
It's not like every job is sh#t.
A lot of these are not the result of aging but the result of trying to be a perpetual child and never learning maturity or how to grow, then life forcing you to.
S#ck it up, kids, it only gets worse.
You'll be doing things you don't like doing in order to go on living, that is
to go on doing things that you don't like - which is stupid.
Better to have a short life that is full of what you like doing,
than a long life spent in a miserable way!
