  1. Lactose intolerance can cause a person to develop diarrhea and stomach upset. Intolerance is not the same as allergy. It's not Anaphylaxis. But it can still make you feel really bad. It's not the only thing that can make you feel bad drinking milk. There are times when dairies give a lot of antibiotics to their cows. I think more and more these days the do it only if they need to keep the herd from catching a disease. But I can tell if there's been an increase in antibiotic use: I get diarrhea like when I take antibiotics. And it doesn't matter the milk. Acidophilus milk at the time still gave me diarrhea. So for a while I got Simple Truth Kroger brand because it uses milk from only grass-fed cows and has no antibiotics. And it agrees with me just fine. A container of milk can say on the label all it wants about not using antibiotics, but you can't fool my body.

  2. Don't laugh at fruit flies! 👍 They reproduce quickly, they live 2 weeks, and they have 4, well-mapped-out, simple genes. This makes fruit flies easy to use for genetic studies. They are used all the time in university genetics classes. These are excellent subjects for study!
