There are Drs. and EMT's and Paramedics and Nurses on here. If they give good advice I would trust it. I don't care who answers my questions as long as they know what they are talking about and any advice you get on here you take with a grain of salt. If you don't like the advice you get, don't take it, better yet, don't ask for advice if you feel you can't get good advice here.
If they seem to know what they are talking about, I'd trust them... mechanics tend to have many accidents and should know a lot about taking care of their cuts and bruises, drug dealers often are quite intelligent and non-users themselves, madmen and taxi drivers are touch and go but can know quite a lot about many things.
I don't want to live in your scared little world, lol.
there are people in the medical profession who enjoy using their knowledge and helping where they can.....some people may be able to help through references to personal experience......
