Is my biological clock ticking and leaving me behind?

I had a birthday lunch with 3 of my coworkers yesterday. One of them just turned 45 but she looks really good for her age. According to them once you reached 25 they just stop counting. It does not mean that they are depressed about the increasing number but it is just that they don’t feel any older. I just turned 29 and the reality of being single in this age is scary. Most men are either taken or have a family and I am definitely not planning to be a home wrecker. Those who happen to be single are looking for a younger, sophisticated goddess where for sure I am out of the picture. But of course they are not going to admit that to your face and they would say something bogus like he is out there he just needs to find you. Whatever! My body is giving me signals of depreciation and these signs scare me. I feel like my biological clock is about to run out of battery and before I can make a move it will completely die out. That is just not fair how only women have a biological clock.
