As one grows older, one tends to arrive at a prime age less frequently.
Let's consider the decades of one's life (with ages as prime numbers):
1st: 2, 3, 5, 7
2nd: 11, 13, 17, 19 (teenagers often seem be in the prime of their lives)
3rd: 23, 29
4th: 31, 37
5th: 41, 43, 47 (a 'midlife crisis'?)
6th: 53, 59
7th: 61, 67
8th: 71, 73, 79 (retirement)
9th: 83, 89
It might be interesting that there are relatively more primes in the 40s and 70s,
which seems to coincide with important transitions in life for most people.
Whether there are infinitely many twin primes (p, p+2) is still unknown.
On another occasion, I may share my mathematical joke about Jesus,
the miracle of 'feeding the multitude', and the Banach-Tarski Paradox.
