I wonder if having kids fairly early (relative to humans) is typical in their society and if their natural lifespans are roughly equal, irrespective of species. Yafya and Gosha should be the same age, within a few months, so they're currently 51 (c126) Edit: Gosha's 54 (courtesy of ktuak, c106, which seems weird given that they looked like classmates, though I guess Yafya's assistant could've gotten his age wrong). Legosi's grandmother is what tore them apart about 36 years ago (c112), so his mother was born when Gosha was 18. Legosi's 18 right now (c120, or 17 before then).
So... Gosha's 54, parents are ~35 (presumably/would be), Legosi's 18, which means they had their kids at 19 and 17, respectively.
Edit: Oh and hey, Legosi's birthday was two and a half weeks ago. April 9.
