Good Lord! So many have all ready passed. Coincidence? Or is there a curse on the Winnie the Pooh series!

Sebastian Cabot died at age 57 of a stroke
Sterling Holloway was 87 when he had a heart attack
John Fiedler was 80
Jon Walmsley is only 49 - hopefully he is around for a while
Hal Smith was 77 when he had a heart attack
Junius Matthews was 87
Howard Morris was 84 when his heart gave out
Barbara Luddy was 70 when lung cancer got her
Clint Howard is only 46 and should be around for a while (and was in a Star Trek)
Paul Winchell was 82

Longevity appears to be a positive side-effect of the honey sucker series

Seems to me that working on Winnie the Pooh is 100% fatal.

Yes, but that's exactly when the curse kicks in! Oh woe is the cast of Pooh!
Cabot knew! but before he could warn the others he was struck down. Some say Holloway faked his death, but then to fully convince the public he ordered his body cremated. Sterling apparently neglected to fully think his plan out. Al Lutz suggested his remains are currently in hiding in South America.
I also read somewhere that Clint Howard's father is none other then Moe of the Three Stooges. Can anybody prove that it is not so?
