I've noticed that about LOTS of people I know, especially when I find out how old they are.
It's like when I was watching an episode of Gulligan's Island with my sister. She commented that the Skipper wasn't really as heavy as she thought him to be back in the day.
In those days, he was considered really heavy. Now he's about average.
Says a lot about our society.
Same with Jackie Gleason.
When I watch The Honeymooners,Norton always made fun of his weight.Gosh he looks thin compared to today’s heavies.
