People born in the year 2000 don't have to try and calculate how old they are when people ask them their age

I usually add 50 to their birth year and add/subtract the remainder from that date. So for 1965 I'd say they were 50 in 2015, so that makes them 58 in 2023. Makes the mental math easier for me.

But I never even realized that was how I did it until I saw your version written out and was like "huh, that's really confusing"
