Elf years to Human years ratio

[Fingolfin of the Noldor]

Elves don't grow old, they are "neither old nor young." After a few years they just stop, and then they look the same forever.

I do not entirely agree(though I totally agrwee in regard to 'yen'). Yes that does seem to be the case especially initially given what is said as to their 'growing up' in the Laws and Customs of the Eldar but Tolkien does actually state in his letters that Elves indeed grow and age but they age 'with Arda' further there is reference to 'cycles'/stages in life in TOlkien's "Etymological Notes on the Ósanwe-kenta" published in Vinyar Tengwar no 41 and associated with the Shibboleth of Fëanor:

The following etymological note pertains to the name Russandol in the discussion of the name Maitimo in the numbered list of the names of the seven sons of Fëanor (XII:352-53). A marginal note against that discussion provides the detail that Nerdanel "herself had brown hair and a ruddy complexion". A note elsewhere in the papers associated with this essay reads: "Elves did not have beards until they entered their third cycle of life. Nerdanel's father [cf. XII:365-66 n.61] was exceptional, being only early in his second."
