When I meditate I sit in a chair. I find the standard postures highly uncomfortable, and they cut off my circulation. My body had never been very flexible, and I broke my back a couple decades ago, an injury which still somewhat limits what I'm capable of.

I don't meditate regularly but I have done a fair amount at various times. (About half of my immediate family is buddhist.) The idea of calming down the internal monologue is attractive to me, but meditation has never put me in a noticeably different state of mind. I feel the same an hour into it as I do right when I sit down.
