Apple Cider Vinegar

Seriously, what is up with that stuff? My roommate actually likes the taste of it. (But I definitely don't.) But it has the same good qualities as vinegar, but less gross. Did you know that if you feel a cold or a sore throat coming on, that if you gargle/drink a bit of watered down vinegar(but not too much) it'll help get rid of the sickness? Gross, yes, but great when you haven't got the time to be sick. And I sure don't.
