60 minutes in an hour
60 x 24 = 1,440 minutes in a day
1,440 x 365 = 525,600 minutes in a year
525,600 x 72 = 37,843,200 minutes in 72 years
but wait - every 4th year is a leap year
72/4 = 18 leap years (each with one extra day)
18 x 1,440 = 25,920 extra minutes
37,843,200 + 25,920 = 37,869,120
37,869,120 minutes in 72 years.
