Lol, I’m 67 and was doing fantastic when I was 64. All I can say is be careful and don’t forget your age.64 and still in pretty good shape body wise. The brain damage gives me problems and the loss of fine motor skills, like my brain telling me I have ahold of something, but I don't. Drop a lot of dishes and glasses. Have all of the aches and pains accumulated from a long time in the service. Not looking forward to what that will be like in 10 or 15 years.
