Sounds like you have a collection of false assumptions.
I suggest that folks
Read the book.
Read all the Biblical Scriptures about Heaven.
Read Randy Alcorn’s book: HEAVEN
There’s a funny, touching aspect regarding the boy’s grandpa whom he’d never met because he was born well after his grandpa died.
They showed him a late years pic of his grandpa and he didn’t recognize him at all.
Later on, his grandma or someone had the idea to get a pic from Grandma of grandpa about 25-30 years of age. They showed him that pic and asked if he knew who it was. He immediately recognized him as his grandpa that he’d met in Heaven.
All spiritual/resurrection bodies in Heaven are around 30 years of age in terms of how they looked on earth about 30 years of age. All the Heavenly visitations characterize them that way. The old patriarchs, Abraham, Moses etc. are also characterized as looking young yet agedly wise and very experienced somehow.
Heaven without wrinkles and sags, that truly is heaven at my age...(chuckles to you)
