Old age for Avalonians.

Genesis, the god of timeto Aphaia, the Sea breeze

I do not know from whence comes this notion of passage of time adversely

affecting Avalonians... old age as a gateway to decripitude? That defies

Avalon logic! If anything old age brings greater potency; aging is an entirely

experience. At least physiologically... in this wondrous land.

So no, there will be no negative side-effects of getting old. Not even if

you're 508 - Zaphod's age - Avalon's oldest mortal.

Written by my hand on the 19th of Mournsend, in the year 1256.
