Dogs, running, reading/writing, music, and of course red-hairs...
All these can help, but like somebody said it can also be a form of escapism. I haven't got a clue on what "meditation" means - to me a load of useless new-age crap. What I find to be the true pass to a stress-free life, even though very difficult, is the process of elimination. In this process you ask yourself what you don't want to be and do (and who you don't want hanging around with). Thus, you gradually remove all stressful events from your existence. Of course removing them all is almost impossible, but you soon find out that just by removing a few the levels of stress become gradually less imposing. In a few months, or years, depending on your willingness, honesty, and independence (specially financial and emotional), you will enter into what I call "useful" or "good" stress. This is the kind you really like, keeps you active, creative and happy...
...the number of people that are total wrecks because they live with someone who's guts they hate, or have a job they despise, never spots amazing me...
