It is impossible to blow up an ecig... there, everyone feel better? hehe, j/k.
I still stand by my point that caution is intelligent, but excessively avoiding activities you love to do because of potential risk is the antithesis of human. I don't mean any offense to anybody, but we are clearly indoctrinated into this cult fanaticism that everything needs to be 100% safe. .. at the first hint of risk we must struggle to avoid it.
Sure there are some risks I will eschew, but not because I'm afraid, it's just because I don't like the activity in question.
Let me tell you a little story about a kid I knew growing up. We were on a baseball team together. Our pitcher was up to bat, great guy... beamed in the face with the baseball (this was only pony league), broke his nose, had to go to the hospital. This other kid on the team like developed this phobia against going up to bat. he would purposely strike out just to get the ordeal over with. he didn't want it to happen to him so much that he eventually dropped off the team because the coach kept harassing him about his lack of performance. he used to be a good player too.. 2nd base, good batting avrg. When that guy graduated (a year ahead of me) he was nearly killed in a car wreck.. someone else plowed into him, not even drunk or anything. now he has a metal plate in his head.
the point is, whether you're safe or not safe, anything can happen. I'm not sayin' be a complete wreckless idiot..information is good, but don't let it work against your better judgement and deprive you of the fun things in life you want to do.
Life: enjoy the ride, nobody gets out alive.
