Please provide a direct quote from Tolkien. Which Half-elf grew a beard in the third age of their lives, or, better yet, which Half-elf even reached the third stage of life like Cirdan? Did Tolkien ever talk about Half-elven hairiness?

Aragorn possessed healing ability, not "magic" ability. This has to do with what Ioreth said: "The hands of the King are the hands of a healer, and so shall the rightful king be known." We discussed this in another thread wherein there is a direct tie to historical English (and French) kings and queens who were believed to have healing ability based on their god-given right to the throne.

There is no basis to say that "Half-elven" blood is a prerequisite for healing, nor was it stated that Aragorn could perform magic. Again, on the Paths of the Dead Aragorn demanding the spirits to fulfill their vow has more to do with Aragorn being the rightful king and wielding the appropriate sword of Isildur. For instance, Elrond, even though he was Half-elven, could not wield Narsil/Anduril and command the dead.

Again, please provide a direct quote that this is the case. The words never came out of Elrond's son's mouths, nor did Tolkien imply it. Legolas' fearlessness is contrasted to Gimli's fear. There is no mention of Elrohir or Elladan in that sequence.

Quicker than whom? Are there Half-elven maturation charts you wish to share?

This is before we get into how Tolkien always keeps the Elves separate from the Half-Elven in terms of language.

Not on the mortal side. Elros is described as Half-elven, but his descendants are not because they do not have the choice. Only those who must make the choice between Elf and Man are given that title. Just like Aragorn and Arwen's children would never be called Half-elven because Arwen had already renounced her elvishness.

Silly semantics aside, the term "Half-elf" is really is more a family title or honorific than a genomic designation, particularly once a choice as to which race is made: you are that race irrevocably; hence Eärendil chose to be an Elf (at the behest of Elwing, who also made the choice to be Elvish and are thereafter referred to as such), Elros was a mortal man, and Arwen was a mortal woman.
