High School USA--Just how old were these folks, anyway?

You may be wondering, just how old were these stars in High School USA (both versions)? Well, I was. I thought it would be a useful resource to list some of the main performers and their ages at the time of the first High School USA (October 1983). 

There is no deep thinking in this post. There isn't even much shallow thinking. I just liked seeing, hey, Dwayne Hickman was almost two decades older than Angela Cartwright! Julie Newmar was only a year older than Burt Ward! Tom Villard was pushing 30!
