I found my IQ is lower then 20 years ago

I’m sorry I started this thread due to some people think it’s self centered and spiteful.I just wanted to post sth that bothers me and interferes my daily life.I know lot of people think I’m spiteful so I’ll never post here again.Good bye and good luck to everyone.

I think it’s a good thread topic, but a bit of a taboo subject with some.
