You can't trust what you read on the net. No, vaccines aren't made from puppies. No, coroners aren't called that because they'll give you the corona. No, the hot singles in your area are all busy creating content for Cracked and have no time to meet you, sorry.
Now, these we've collected here are the opposite -- they seem to be bullcrap, but they're all backed by science. Nothing but the unvarnished truth here. (OK, we might have varnished a couple a liiitle bit, but you won't find any lies.)
