Q: Does age matter?

I've had to deal with this question recently. Older or younger, does it really matter? My stupid rule: 3 years and older. The upper limit has been tested in the past a few times, not so much the lower end. This is not to claim that maturity is matched if the guy happens to have been born 3 years before me. Here's another adage: rules were meant to be broken. True, after a certain point, age doesn't matter, but what point is that? As a friend mentioned before, we are now in the middle, gray area, or in limbo. Is age just a number??
