It is, without a shadow of a doubt, an ad. Blocking this shitty meme community. Btw, off topic and no offense, but I thought you were woefully miscast in The Winds of War and War and Remembrance. Cheers!
Lactose intolerance is the norm for humans. Somehow this doesn't get communicated since practically no one knows it. Up until somewhat recently all humans were lactose intolerant. Iirc tolerance started with starving Europeans making full use of cows a few thousand years ago, then over time people became able to tolerate it.
Experts estimate that about 68 percent of the worldās population has lactose malabsorption.
All that to say yeah, it's a very common condition and most people who have it probably still eat lactose as it's not all that bad to get the shits. Come on, it's cheese and ice cream we're talking about here. And pizza. Even if the consequences were awful, humans are also pretty good at ignoring consequences when deciding if they want something they really like
But how are those percentages distributed globally? If the 32% mostly resides within middle/west europe and american continents with a minority in Asia it totally makes sense why we have that understanding in the west.
Not everyone in the West is fully European, but even if they were, a significant portion of even those people are lactose intolerant. I mentioned the global stat 1) because it was available 2) to illustrate the point that just because we evolved something recently doesn't make it the standard way for a person to be.
Lactase persistence has actually evolved around a dozen times independently. Most of the genes originated in Africa, but the one Europeans have evolved in the Indus valley area before the Indo-aryan people migrated to Europe.
Last night at the grocery store I saw 2 for $1 small hass avocados and nearly fell over dead. I am now retired, independently wealthy, and bought 4 homes. 3 to live in and 1 to rent to the suckers who missed the deal.
