Diagnosis
Hi Everyone!
I'm new to all this and using this site but I'm sooo glad that it's here as I could really use the help with my dad. He's aging and doesn't like it, lol! But he thinks that the Docs are just going to give him a pill or something and he'll be all better/like new?!

They have referred him to PT's who have told him that he just has to move- the more he moves his body the better/easier it will become- but he seems pretty set in his ways. He's been retired forever but doesn't have any hobbies that keep him moving, so getting him to move is a challenge.

I'm hoping for some thoughts, advice, ANYTHING that will help me out. Thank you!
Steve
