Happy Birthday to me!
Birthdays just aren't exciting any more. I guess you could consider the decades as significant milestones, but I don't really buy that. Thirty wasn't really so black. In fact, I still felt pretty twenty something well into my mid-thirties. Around the middle of that decade I'd definitely moved on and felt solidly like an adult, as opposed to a young adult.
Forty wasn't really that big of a deal either with the exception that with adulthood came more stress and a more sedentary lifestyle and evidence that my adult lifestyle was creating problems. It was around 39 that my weight and blood pressure peaked and sounded an alarm that my lifestyle wasn't sustainable. Come to think about it, that was also when I finally resolved my doubts about the church and moved on from the teachings of my childhood. I stopped racing motorcycles, took up running, lost 35 pounds, and quit going to church. I take it back. Forty was a pretty significant milestone in my life although I didn't think about it at that time.
Who knows what major changes may come, but the next big age milestone I foresee is retirement. I suspect that with the emerging demographic trends that is likely to push out to 70 by the time I get there.
In the meanwhile my doctor gave me a pretty stern lecture about taking care of myself when I went in for a physical. After running some tests I found out that my blood sugar is fine, my cholesterol is excellent, my blood pressure is now under control and good, and a heart CT showed that I have zero hardening in my coronary arteries. Like it or not, I'll probably be around for a while.
