Optional exchange of DNA

Vitus is a movie about a genius child piano prodigy who just wants to be “normal.”

This scene of the movie actually made me laugh out loud, stop, rewind, rewatch and laugh all over again.

Vitus, who’s 12, is having dinner with his former babysitter, whom he has a mad crush on.
---------
Vitus: Well, statistically, women are usually seven years younger than their partners, but that’s really stupid because men die seven years earlier, so women are widows for 14 years... We would die at the same time. Besides, a woman’s libido is at its peak 10 years later than a man’s. That’s why so many relationships fail. Women should be older than their men. We would make the perfect couple. Isabel, you’re the love of my life.
Isabel: And what about sex?
Vitus: Well, that could wait for a while. It’s just an optional exchange of DNA anyway.
