One refuses to move out of their comfort zone, and wants to look only at the grandkids, while he wants to play in a rock band, or move to another country, do something exciting before he rots.

Men aren't interested in stagnating, the young woman still wants the sexual stimulation while the old one went off it years ago, but is more interested in keeping up appearances, while he wants to let loose and grow old disgracefully.

Well that sums up my life anyhow! lol
