Thanks to my fellow yogi Clare Townes for sending me this link. It just made my day. Click the link and read about chair yoga at senior centers, even savasana for the bedridden.
Yoga, which is mostly about breath and awareness as the article states, is for everyone.

The Well: bodymindheartspirit 
Hi there. I’m so glad you posted something on chair yoga. Leeann Carey, an amazing yoga teacher, says that senior citizens can really benefit from doing modified sun salutations. She has a free yoga video on this that I think your readers might like: http://planetyoga.com/yoga-blogs/index.php/free-yoga-video-modified-sun-salutation/

I like this modification of sun salutation–doing it from a seated position would allow people with knee, ankle, or foot issues to maintain some hip and upper body flexibility, which increases lung capacity and massages internal organs, which increases feelings of well-being. It reminds me that some yoga is always better than no yoga. Thanks for sharing.
