FF - the difference is the men sign their first contract which is guaranteed and can set them up for life even if they do not make it through their first game, the women do not. They may reach a point of financial security after 5-10 years if they are really good, and a few of them (one or two every few years) may reach that point a little earlier. For the vast majority, they live a vagabond life between the US and foreign teams and reach retirement with less to show for it than if they had gotten out of the sport and started a different career on graduation. And for those whose bodies break down, part of the issue is they play 12 months a year - Morgan finished a 40 game schedule in April (2 preseason games) had a 10 day hiatus and started her professional career. If she hadn't gotten injured, those ten days would have likely been the longest break from competition and training camps until next spring at the earliest and possibly for the next x number of years.
Most men's professional athletes take at least a month off a few times a year to recharge mentally and physically every year, and are only in competition or intense training for at most eight months each year.
