True. That is what makes it an effective fantasy.

In this movie there are numerous miraculous healings and even a small animal brought back to life. A 108 year old man that was given the gift of a long lifespan being able to kneel and sit on the floor isn't the least believable thing that happens in this movie.

Do you think he wants some cheese?

The actor who played him was in his 80's at the time of filming.

It would be a miracle too live too be 108 even 110 or 120 it's in the genes why some people so long many people have made it past 100 even past 110 if you had family members that lived to be 88 89 and 103 you could easily live too 110 and 120.

Well if the lifespan of a mouse is 2 or 3 years and Mr Jingles is alive 70 years later, I think Tom Hank's character would be alive for centuries.

that's the impression I always got too, was always left wondering how long John's magic would have kept him going.

The nursing home would have just thought he was in amazing shape for 108. He would probably have gotten more attention in the coming years, as he continued to be spy in his 100s.

It's possible that he believes that at 108 his old age is now due to John Coffey and has started lying about his age. Could be that he is telling people that he is "only" 90 years old or so.

The thing that occurred to me though is that when he was admitted to the home they would have had his date of birth. It was surely noticed by staff that he was 108 and therefore surely would have been known around the wards. Especially his friend.

The average mouse's life span is only two to three years.
There are 8.2 billion people in the world. 8.19 billion of them have never heard of and don't give a fuck about Charlie Kirk. Get over it.

Well yea but it's johns magic that's preserved him. The mouse would've been around 60 years old and that's 8/9 times an average mouse lifespan, and it was pretty mobile.
