Happy birthday, seems like only yesterday that I hit the big 40. That was 29 years ago if I remember correctly. Don't believe all the downhill BS. Just because you grow older doesn't mean you have to grow up. The good things I enjoy about growing older is 1) grandkids, 2) bills are paid, 3) every day is Saturday, 4) money isn't always a concern (took some good advice when younger about investing for the future) plus a lot more reasons that at this age you forget. LOL
Have a great day.
