I personally felt oldest at 29, like my youth was about to slip away forever into all out manhood. It was about to get real and my friends made sure to point that out. The weirdest thing is; after the celebrations were over, nothing had changed.
After some time I felt pretty darn good about my trips around the sun (no disrespect to the flat earth society.) It was actually a relief to let go of the anticipation involved with approaching some kind of imaginary pinacle. I also found that my values reflected the point that I am at. In turn, I am and always have been happiest where I'm at. This is 'Now.'
My brother once had a councillor tell him; (in horse stance) 'You got one foot in the past, the other in the future. Problem is you're pissing on today.' Very wise, she must be old?
It sometimes appears that ladies have a harder time with aging? I'm not totally sold on this idea but I'll humor it only so much as to say;
So let the truth be told, don't get it twisted.
