Across the world, I'd say.

How old are you?

@@josephinelol2214 You first!

@@josephinelol2214 graduated in 75. people graduate from HS at around 18. 75-18 = 57, which means 1957 is the DOB or somewhere close (±1 year). So, 2020 - 1957 = 63. So the final answer is 63 (±1) years old. Literally took me 5 minutes

That's because we acted "normal" and not mentally challenged.

Honestly having a family member with dementia myself I'd call that worse...

To learn. Duh!
