Without making this into an IMHO:
Have there been any studies as to whether yoga actually does anything healthwise? I’m about as spiritual as a bag of bricks and I doubt that will change. However, I do like taking breaks from life, and rather than just sit in my apartment and stare at the ceiling, I thought I might try yoga. Again, please don’t make this into an IMHO; I just want some hopefully scientific facts about yoga to see if it is anything more than weapons grade bologna.
