i feel like lactose intolerance is v common in the US, if that's where you're from?

like i've known people who lived short-term in the US for a few years n came back lactose intolerant. after being tolerant their whole adult life up till that point. n i've heard the milk stays for a long time whereas here it stays for a few days max. lactose intolerance is a lot less common here.

but i think it's also that we weren't sposed to keep drinking milk after being weaned off mother's milk, in the first place.
