72 is a Good Number

I am 72 years old today.

72 is a good number that is divisible by 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. It has the same number of divisors, twelve, as 60, which is divisible by 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60.

84, 90, 96, and 108 also have twelve divisors, so I look forward to reaching these ages. (Realistically, any age past 90 is a stretch. My father lived 87 years and my mother 91 years.)

120 is the first integer with 16 divisors. 144 has 15 divisors, because 12 is counted once in 12 * 12 = 144.
