People "from the 80s" don't necessarily had to have been born in the 80s. It's the time frame in which you grew up. So a guy born in 1975 was most certainly a 80s kid and he'd be closing in on 40. Tell me, do you really recall that much from before you were 5 or 6? I know I really don't, I recall some memories and have a general vague hazy picture of my years during age 4-6 but not with much clarity.
Kids "from the 80s" were born in 1974-1983. Later then that and I'd say you're more of a 90s kid.
