Well my behaviours aren't obtrusive, if thats what you mean, and I am fine with them, considering that.
I have tried meditation and yoga, but I could never get the motivation required to build a habit. One of the main problems with meditation is that it is all about stillness, which can be very hard for somebody with ADHD! I mean, relatively speaking, a shower is a bit like a form of meditation for me, so maybe people of ADHD do practice a form of meditation by engaging in these activities.
