I prefer to think
that somebody is indeed more than hundred years old - I've included option at all because it was possible to have someone that old, even if improbable. Next time I feast, I drink his/her health (even more so if s/he is unscrupulous cheat
)
edit: Just thought how wondeful it must have been to read the Hobbit as it first was published, and probably be in correspondence, or even meet with JRRT himself!
