I just turned 60. I still feel like when I was 30. I look like I'm 45 (runs in the family). I tried to get the senior day credit at the store the other day and they laughed at me. I finally showed them my ID. My mom who is 84 is her husband's caregiver (he has Alzheimer's). I hate it but she caths him x3 daily, dresses him, the whole shot. The thing is she still has time to drive to lunch with her friends, do the shopping, etc... My family doesn't die off until we're 100 and we remain sharp as tacks mentally so there you go. I admit it; we're tough. Did I mention I had a child when I was 45...yea, I'm helping him with his homework after I do this.
Age is a state of mind unless you have debilitating disease and then any age is tough. When I read the younger ones complaining they feel so old it's sad. I lift weights, die my hair, and drink Myofusion post workout. Don't forget the over 2 liters of fluid a day. If you want to remain sharp, you need to work at it!
