How old do you feel on the inside?

Still pondering this age thing.. A very dear friend said to me today "You sure don't look 70."  Now I've learned a few things over the years and one of them is to never ask the next logical question "How old do you think I look."  I don't want to know.  I'll just take her comment as a compliment.  But then she asked an interesting question "How old do you feel on the inside?" After a little thought I said that  I feel like I'm in my 40's.  I remember a conversation with my father one Christmas day when I was in my 50's and he was in his 80's. I said to him, as I was busy getting the dinner on the table, that sometimes, even though I'm all grown up on the outside, I feel like a little kid playing at cooking dinner.  He laughed and said "You know, some times so do I."  Isn't that great?  I plan to stay as young as I can as long as I can on the inside, and in the meantime I will avoid mirrors.
