Do the young still fall in love, or is that mechanism obsolete by now, unnecessary, quaint, like steam locomotion? He is out of touch, out of date. Falling in love could have fallen out of fashion and come back again half a dozen times for all he knows. (2.27)
Clearly, David has been out of the game for a while.

"After a certain age, all affairs are serious. Like heart attacks." (5.62)
Here, David responds to his lawyer's question about whether or not his relationship is serious. Nice play on the heart imagery here, David. You can see love as a heart attack, since the heart is supposedly the seat of desire and emotion, but heart attacks are also not uncommon afflictions among the aging and elderly.

Perhaps it is the right of the young to be protected from the sight of their elders in the throes of passion. That is what whores are for, after all: to put up with the ecstasies of the unlovely. (5.82)
David's really knocking himself down here. Elderly and unlovely? Cry us a river, man.
