You know what is worse? Not getting old.
I keep a photo on my desk of me with my arms around my two closest friends. One of them lived me while his house was being built, my kids babysat his kids, we all boated, BBQ'd, celebrated, shot pool, traveled, etc etc together. Ten children between us. When anyone asks me about the photo I tell them the same thing. I keep the photo on my desk to remind me how precious, and fragile, is the gift of life. You see they are both dead. Get old? Heck, one didn't make 50 and the other made it by 2 years. 6 children without a father, 2 wives without a husband, four parents who had to bury a child and today, two grandchildren that will never know their grandfather.
I accept the aging process with gratitude. Sure, I do all I can to take care of myself (a discussion that may be of interest here, diet, exercise, supplements, etc) but on this day, and every day, I give thanks to God for another day on this planet.
