2. I can speak to the shoulder issue.

I've managed to break both of mine over a period of time, and both are bolted together, one with a bone graft.

I don't have full mobility in either, but I promise you that you can still lose weight. I walk all the time, but if you're stuck inside, use an exercise bike (got one secondhand for 25 bucks years ago).

Also, my small town has a senior center and a couple community centers which have treadmills and other exercise options.

I've belonged to a gym forever, and just found out that all this stuff is offered for free for seniors! Staying active in any way you can will do wonders for your outlook on life.
