“How old are you?” asked young Fred.

“I’m 42, buddy.”

“42 days?”

“No, 42 years!”

“Oh. But how many days is that?”

It is not quite 7:15am on New Year’s Day. I have not yet had my coffee. $42 \times 365$, plus however many leap days, plus however many days there are since my birthday, is not something I am currently capable of calculating.

“It’s $21 \times 730$, and seven 73s are 511, which makes the whole thing 15,330. You’ve had 5 leap years in the 80s and 90s, a futher 5 in the 00s and 10s, and it’s 46 days since your birthday. You’re 15,376 days old.”
