I definitely care less as I have gotten older. And I say what I think which I never used to do. I have become very hardened now to people I don't like and I tell them what I think of them cos I just don't care any more. If I have things on my mind, and I can't sleep, I breath in deeply thru my nose thinking only nice things, and then blow out through my mouth imagining I am blowing out all the bad stuff (or imagine the nasty people I am thinking about being blown away in a hurricane). It seems to work and calm me down, and I get off to sleep better. Maybe its just in my mind, but it works for me.
