If they made it to at least 15, then probably on average somewhere between the 40s and late 50s from estimates I’ve seen.
(1,000 generations being probably < 30kya; there appears to have been a fairly radical expandsion in lifespan around 30kya, before that most estimates I've seen would have adults, by thrbsame definition, averaging sonewhere in the mid-30s or so.)
