Inevitability of death (revisited)

[Tuor in Gondolin]

Tolkien did also make it clear that Valinor itself was not really deathless, but that the presence of the immortal Powers gave the place its apparent lack of death and decay. The very power that makes Aman seem immortal and unchanging would present a danger to mortals (as the flame that attracts moths also kills them, as I believe was noted in the Akallabeth).

This could also relate to Luthien's speeded up
life caused by wearing a silmaril.

And did Valinor have seasons? Without them I'd think it would
be relatively uninteresting, like living (long-term) in a boring
climate like Hawaii. I'd much prefer somewhere like Minnesota
or Argentina to Hawaii climate wise, especially if you're there
elfwise for milennia.
