These bees are generally pretty safe to be around. I do worry a bit about small children but they should be watched by parents at the age that they might get in trouble stepping on a bee hive. We need the bees for making our food, so I think it is best to live and let live. Those people who are very allergic to bee stings should probably carry an EpiPen with them just in case they are stung.
Certainly getting stung once in awhile doesn't stop me from getting out there and enjoying things but wasps in particular can be really painful when they sting you multiple times. (Maybe we need to genetically alter our skin to stop bee, wasps, mosquitoes, and bullets - Kevlar skin, I should patent that, LOL)
You are right about that Epipen because they can die really. Sometimes my brother is so allergic that he wheezes but he had no asthma @lightsplasher
I couldn't care less about being stung because I get pricked during dialysis with large needles four times per week. :/
