I am 34 years old. I am not old, or elderly, or geriatric, but I am aging. In a year, if I were to get pregnant, I would be classified as being "of advanced maternal age", which means there would be an increased risk of birth defects due to old eggs. My hair is turning silver (and it looks so good, I figure I'm about a year away from cutting the colored length off), I find myself holding papers away to read them, and my shoulders are sloping to the point where my bra strap keeps slipping off and I'm shopping around for tiny calcium supplements. And that little line between my eyebrows that comes from furrowing my brow at stupid people is now about as deep as a bullet hole.
When I was young I was so stupid. Seriously, I can look back on just about any moment of my life and feel embarrassed for myself. But I was young, and thin, and carefree. I wish I'd realized it. I wish I'd worn bikinis, and taken compliments better. I wish I'd enjoyed it before it was gone. Self-esteem should exist in the present tense and not just in hind sight.
