Die saving people or die trying to

I had soo many dreams of me becoming a superhero!!
but that is just silly, so what I actually want is to save someone, like being in the police,firefighters or rescue team!!!
I want to do something ecxiting and dangerous!!
the problem is that i will never be able to do that I’ll just try my hardest to save people, by convinsing themselves not to kill themselves and that type of stuff!!!
Then later on I’ll try to get into firefighting!!!!!
