Fat, or adipose, tissue isn't just inert blubber threatening our health and self-esteem; it's a functional part of our bodies, interacting with other organs to boost muscle and brain metabolism.
Like everything else, it loses functionality with age, but new research shows that rigorous, regular exercise can help keep your fat fully functional -- at least, the fat you don't actually burn off. And fat cells that are healthy and happy can help ward off a lot of human diseases, from cancer to diabetes.
Body of Knowledge
There are approximately 600 muscles in the human body, divided into three main types: skeletal, which allow for movement; smooth, which make up internal structures like the digestive tract and blood vessels; and cardiac, your heart. The biggest muscle is the gluteus maximus in your buttocks; the smallest is the stapedius, which stabilizes the smallest bone in your body -- the stapes bone of the middle ear.
Get Me That, Stat!

Hereditary sensory and autonomic neuropathy is a rare neurological disorder that affects the nervous system and, most notably in those impacted, can cause the complete inability to feel physiological pain. But if that sounds like a benefit, it's not. People with HSAN have been seriously injured because their bodies didn't warn them of imminent harm. HSAN also is characterized by hearing loss, seizures, sleep problems and progressive dementia.

Q: What is the strongest muscle in the human body?
a) The tongue
b) The jaw
c) The heart
d) The gluteus maximus
A: A popular answer is a) the tongue because it's all-muscle, extremely agile and always moving. But strength is not easily defined, and there is no single answer. The glutes of your buttocks provide enduring stability to stand, walk and run. The muscles of the jaw can apply up to 125 kilograms of force in a single bite. The heart must work throughout your life or there is no life, beating an estimated 2.5 billion times in an average lifetime.
Fit to Be Tried
There are thousands of exercises, and you've only got one body, but that doesn't mean you can't try them all: A bridge kick engages the whole lower body from the core down. Lay on your back with your knees bent up. Your ankles should be in line with your knees. Place a cushion or pillow in between your knees and squeeze to keep it in place. Lift up through the belly button and squeeze the glutes to engage the core. Push your arms and hands down into the ground as you pull your hips upward. Once you reach this bridge position, keep your glutes engaged as you kick out your left leg. Lower down and repeat on the right side. Make sure you keep your kicks slow and controlled.
