Yep, love really *is* complicated. Hormones, neurotransmitters, sensory neurons, oh my!

Sweaty Business When was the last time you thought about your sweat glands? Sweat is actually pretty cool. It keeps you from getting too hot, guards against bacteria by making the skin acidic, and even drains away extra fluid and electrolytes from the blood. Hello to night sweats after a heavy night of drinking! There are 2 main types: apocrine and eccrine. Sometimes the eccrine sweat glands get a little too excited about their cushy job, and ta-da: hyperhidrosis happens!  These lucky people get extra sweaty when their sympathetic nervous systems kick into gear.

Many of you have written in to suggest making some sort of graphic showing where all the guts and glands live in the body, and I've finally gotten around to creating one. It's even got rollovers so you can learn more about, say, your pineal gland, should you have time to squander. For the purposes of simplicity, we've made the body a hermaphrodite -- she's got a uterus to go with her prostate and testes! We'll call her/him Hermie.
