My folks are in their mid-eighties, as are my wife's. My mother-in-law is very ill, in ICU, and we will likely be losing her within a week. They live in central NY.
I just wanted to tell you younger guys (I'm 58) that if possible, spend time with your folks while they're still able to enjoy it. Go fishing or boating with your dad. Those were things my dad and I enjoyed doing together. We also enjoyed snorkeling and body surfing. We both loved the water - salt or fresh. Ended up with all sorts of crazy stories which my mom still wonders how we survived. My dad always had a great sense of humor and is sort of a cross between Abe Lincoln and Kramer (from Seinfeld) in both appearance and action - if you can envision that. My 18 year old son said that the other day, and it really fit.
My dad would love to continue doing all those things, but he really can't anymore, at least not safely. It's hard watching your parents age. So enjoy doing things with them while you still can, so you don't regret it later. Someone mentioned this to me years ago. I took it to heart as best I could while trying to raise my own family, and am glad that I did. Still, I can't help but wish that I had done more. Time passes so quickly - even more so as one gets older.
