Prime numbers as we get older

Don’t you love it when your age is a prime number? I do. Currently I’m 37, a prime number! That only happens twice in your thirties (the other age being 31).

Which decade of your life has the most prime number birthday ages?

List of prime number ages, sorted by decade:

2, 3, 5, 7,

11, 13, 17, 19,

23, 29,

31, 37,

41, 43, 47,

53, 59,

61, 67,

71, 73, 79,

83, 89,


101, 103, 107, 109

Your first decade (0-9) has four. Then the following (11-19) has another four. You’d think the prime ages would diminish over time, but in your 40s, the primes jump up the three times. And again in your 70s. If you are lucky enough to live over 100, you’ll hit a prime age four times!
