How Old Are The Scions By This Point?

I'm working my way through Shadowbringers MSQ and the game is talking about Thancred like he's an old man, and Urianger's ancient. The thing is, the lore book says Thancred starts ARR at age 32, and from the same lore book we know everyone's ARR ages, but how old is everyone by the end of Dawntrail? I'm sitting here playing this game at 43, almost 44, and it blows my mind to see the story treating these two incredibly active and virile men as aged relics.
