True. Fertility in men can be helped somewhat through freezing sperm. But sometimes it is an excuse. As much as I detest the recent misandrist narrative, I do know very well how men get, and we are constantly bombarded with 24 year old women, or 20 year olds who will become 24 year olds, being the picture of desirability.
If I ever have a daughter, I'm putting her straight into JKD or Krav Maga when she's able.
