You don't really get wiser as you age. Just scarred by experience. It takes me longer to do some of the things I used to do quicker. And I'm also doing things that I wouldn't have been able to do earlier in my life because you learn a lot as you progress through the years. It's a mixed bag.
I actually like what I do professionally. So, I'm not looking forward to retiring. I'm actually kind of dreading having to do that because of physical limitations or being regarded too old by others. I plan to stay active as long as I can. Regardless of financials. What comes after that is basically waiting to die. Nice if you can make that enjoyable and stretch it a bit. But for most people that's not a huge part of their life, or the best. Or what defines them for others when they are gone.
