1) You will get stung on the eye from time to time and look like a clown for a day or two. This is in fact character building, but embarrassing if you need to get married or something like that (I know someone who had this happen).
2) Beekeepers can get a venom headache if you get stung a lot. This is a bit like PMS and makes you say things you should not say. Venom headaches cause people to be too honest to other people. You may end up telling somebody who is an idiot that they are an idiot. That person may then act like an idiot would and punch you. This has happened to me.
