How long did the great-grandfather live? If he started things in the 1999 and Gabriel is 20-25 in the 2100s it means that he must have been about 110 or so when he and Gabriel hung out and talked.
Author's Response: The current year is 2064, when Gabriel hung out with his great grandfather he was a child. The great grandfather was born in 1980, so in the 2050s he would have been in his 70s.
