He will feel the accomplishments in a positive manner, even though it will more than likely wear him out (and you also, worrying about him)! I couldn't wait to get back to work and attempt to start "getting back to normal", whatever that means. (LOL) And yes I overdid it quite often (and still do, with criticism from my wife/caregiver, but a "go get 'em" from the Dr.'s, I'm sure they mean within reason).
I guess what I'm trying to say is "If it feels good, do it" and let him go. He's feeling as though he has his life back, so he's making the most of it. I hope this "logic" makes sense to you. By the way, hot dogs are a GREAT thing. I remember the first one I cut up in little bits and thouroughly enjoyed, (I think JAM or JoAnne originally suggested it!!) MMMmmm, it was Wonderful. Funny that was brought up, that's exactly what I had for dinner tonight.

Best wishes,
Steve
