3 hour bike commute - 1 hours car commute = 2 hours to spend with wife kids.

24 hours a day = work time + commute time + family time + sleep time

By algebraic manipulation:

family time = 24 - ( work time + commute time + sleep time )

Assume sleep time = 8 hours, and work time = 8 hours

family time = 8 hours - commute time

Assuming 1 hour commute, commute time = 12.5% of family time.

Assuming 3 hour commute, commute time = 37.5% of family time.

Spending almost half of available family time as commute time = single again.

That's the way my wife does the math, and she's a Phi Betta Kappa.
