Is head banging hazardous to my health?

I am the front man for a heavy metal band that is steadily growing in popularity. During shows, the whole band head bangs, but I seem to go a little bit harder than everyone else. Every morning after a show, I wake up with stiffness, soreness, and slight swelling of my neck and upper shoulders. Lately, I have been thinking that maybe thrashing my head around as if it isn't connected to my body is a bad idea.

My question is this: Does head banging cause any permanent injury that I should be concerned with? If so, how could I head bang differently to lessen the injury?


How can I get rid of pubic lice?

1) I have recently discovered that I have what appear to be crabs in my pubic hair. They are itchy and annoying and appear to be laying eggs. How do I get rid of them?

2) I think I have pubic lice, a.k.a. "crabs." Do I need to see a doctor about this problem, or is there over-the-counter medication of some kind I can use to expel the little buggers from their new home? Also, I'm curious as to how I got them since I haven't had sex for several months and this is a recent development. Can one contract this problem from sharing clothing, towels, or bedclothes?


Does exercising on an empty stomach maximize fat burning?

I have recently learned that in order to burn fat as a fuel, your body requires carbohydrate. Up until this point I had been doing cardio training first thing in the morning on an empty stomach, as I had read that this is optimum for fat burning. However, now I have a small carbohydrate snack before I train in order to prevent my body using lean muscle tissue as a fuel. Today I have again read in another book that training on an empty stomach first thing in the morning burns the most fat. I am a little confused over the best thing to do! I train with weights twice a week and do cardio three times per week. I do want to maintain my lean muscle, but am looking to reduce my body fat.
