> The part that's emotionally harder is that I'm sad I won't be there when my kids are approximately my age. I'd love to be around longer to help if they have kids, etc., but statistically, I don't think it's too likely.
This bothers me a lot, too (although I had my kids a couple of years earlier than you). Not just the physical presence, but also being physically and mentally fit when they're adults. I'd like to do sports, travel with them, help them move between apartments. I'd like to be mentally on the same page, not an old grumpy fart not understanding what they're thinking about. All of that can be done, but it simply gets more difficult with a larger age difference.
