Do you think that Michael would have had more kids if he had lived longer?

I guess so .
He loved kids. If he'd find someone that really loved him , probably he'd be a father again.Id hope so.
Or maybe he'd adopt some kids. He once said that he wanted to adopt every 2 kids from any continent . Which means 14 kids. Loool , maybe he was just kidding back then x)

I think so, he loves children!

Yes, Yes, Yes

you are right on the money that he wanted to adopt two children from every continent, VSBeatty and before his death in 2009, he wanted to have a 4th child, a girl for Paris.
