Today, I celebrate the (binary)11111th anniversary of my birth. That makes me 31 years old. That’s 25-1. The next one like this is (dec)63, and I most likely won’t see the one after that. 31 is a prime number, and one whose digits sum to a square (22)
From the prime curios page, we also find the following:
- 31 is close to
3
- 31 is the third Mersenne prime.
- Buddha preached on the 31 levels of existence in our universe.
- 31, 331, 3331, 33331, 333331, 3333331, 33333331 are primes
- Lance Armstrong, in 2003 (at the age of 31), became the 2nd person ever to win the Tour De France 5 times consecutively, beating the runner-up Jan Ullrich by 61 seconds. Note that 2, 5, 31, 61, and 2003 are all prime numbers.
