Well I am that older guy looking in the mirror. I have had my three score and ten but do you know what? It's all a matter of perspective. I have had a good life , there are things I would change if I could go back but there were so many things I enjoyed and so many events that I never could have foreseen. Here I am, 70 years old and still exploring that unknown territory we call the future. My advice to all the young folks out there, do as @jwolf says seize the day. Carpe diem.
