At 23 you meet new people all the time. A decade later you barely ever do (in my experience), so you have to make an actual effort to meet people, especially to date them.

I don't know a lot about Japanese culture but here in the UK the 'jumping into bed with everyone just to see what works' phase seems to be over by her age (30). Or maybe it's just me...

Weird. My impression is the opposite. In youth, you have time to go slow, but as you get older and busier, you jump into bed to see what works without wasting any time.

Why would you go slow when you're a youth? You've got hormones and energy the likes of which you'll never see again!
