28, a perfect number

Today I turn 28... and I’ve learned that it’s one of the 39 known perfect numbers.
What is a perfect number? One whose proper divisors (excluding itself) add up to the number itself.
Like this: 1 + 2 + 4 + 7 + 14 = 28.

By the way, many thanks, Javi (for the congratulations and for the curious and interesting bit of information). ;)
