58/m, married, retired early in 2011 due to major vision loss (retinitis pigmentosa) which is progressive and continuing. That and several injury problems in recent years limit my choice of activities. I have arthritis in both knees and in my neck, as well as elbow issues. Knee replacements are not too far away. There's another issue, probably heart related, that seems somewhat controlled by meds, but I think the meds have reduced my metabolism also.
Working on controlling snacking and keeping up with exercise. I tend to feel stressed easily and react with compulsive snacking.
I've never been pleased with my physical fitness - I don't have a lot of aptitude - I've mostly gotten past using that as an excuse, but I'm still inconsistent.
