Valian year?

[Mumriken]

I just looked through some threads on this forum and found this quote:

a great multitude of creatures, without fear, of many kinds: animals or moving creatures, and plants that are steadfast. There, it is believed, were the counterparts of all the creatures that are or have been on Earth, and others also that were made for Aman only. And each kind had, as on earth, its own nature and natural speed of growth.'

'... all those creatures that were thither transplanted or were trained or bred or brought into being for the purposes of inhabitation in Aman were given a speed of growth such that one year of the life natural to their kinds on earth should in Aman be one Valian Year.'
In this text 1 Valian Year = 144 Sun Years. So that if a dog usually lives 15 years in Middle-earth, it will live 15 Valian Years in Aman or 15 X 144 (for Sun Years). It could not get sick, seemingly, for it was also said: 'For in Aman no creature suffered any sickness or disorder of their natures; nor was there any decay or ageing more swift than the slow ageing of Arda itself.'


If this text was really going to stand, in all ways, for an ultimate conception anyway.

So if at the end of the lord of the rings, Frodo, Bilbo and Gimli goes west. Would their natural lifespans be expanded. Frodo was 50 years old at the time of the lord of the rings. So if one valian year is 144 sun years. Would Frodo live for another 5760 years in Aman and Bilbo maybe a couple of centuries longer? Gimli was 139 years old and a dwarf lives to about 250 years. That is about 111 more years to go. If one would translate that into valian years that would be 15984 more years to go. I don't know I just found the thought of a 6000 year old hobbit to be interesting.
