Belated birthday wishes! I am currently 68, turning 69 toward the end of October. Sometime in the past 4 or 5 years I began to feel much older than I had previous to that. My knees now feel like they are 80 years old. My brain functions about like it did when I had a colicky newborn forty years ago, which means it didn't function then, either. I still WANT to do many things, but frequently find that I no longer have the capability or the energy. I catch myself saying I am old, but I have re-defined "old" as 80. So I guess I am no longer young, but not exactly old yet, either.
