As a 41-year-old, I'm incentivized not to believe that math is a young person's game, and so agree with you; but one could try to disagree with you by suggesting that it's a sweet spot: the years, say, mid-20s to late-30s are the time when the accumulating benefit of knowledge and experience has not yet been outweighed by the accumulating burden of age and responsibility. (And one could, of course, argue against this argument; I think that there is no valid conclusion but "it depends.")

I would also suggest that there probably are breakthroughs achieved by teenagers living at home with their parents! I think, for a recent example, of https://www.wuft.org/news/2022/02/18/buchholz-high-school-st... .

Not sure why you were arguing yourself in circles here. Yes, it depends. Everyone's life and life circumstances are different. It's a mistake to overgeneralize about what life is like at certain ages, and use that as the basis for ageism. "Older people are more distracted" just seems ridiculous to me.
