This month, we tell you why back cracking feels good, how you'll lose your hearing, and six facts about Conan the Barbarian.
Answering all the questions you never knew you had (and some you did).
Why does cracking my back feel so good?
Robert Tonne, via e-mail
“When you get adjusted, the joint moves and a pocket of nitrogen is released, which is what the ‘cracking’ refers to,” explains Jezariah Munyer, a massage therapist at Chiro-Medical
Group Inc. in San Francisco.
And why does it feel so good? “It resets the nerve so it’s no longer irritated and also increases your circulation, which gives you that kind of flush feeling.”
Sounds plausible, but let’s ask a real doctor! Says Andrew Sama, M.D., a surgeon at the Spine Care Institute at the Hospital for Special Surgery in New York City: “When the joint capsules in the spine are stretched, pressure causes natural gas in the synovial fluid to come out of solution and ‘pop.’ This sense of release feels good to some, who get relief from cracking their joints.” Just say yes to crack.

DUMB QUESTION OF THE MONTH
One of you actually asked this: Would a suit of diamond armor make me invincible?
Shawn Dempsey, Kansas City, KS
X Stephen Lenhart, Ph.D., of the geology department at Radford University in Virginia is here to literally shatter your fantasy. “Although diamonds are an extremely strong material, they are also brittle and wouldn’t stand up to much in the way of impact. So the short answer is no.” In terms of warfare, diamonds would be more effective as bullets. Glamorous bullets!
35.09 = According to Japanese researchers, this is the exact age at which time hits home
and skin damage becomes longer-lasting and much more difficult to prevent…for women. Did a skin-care company preying on female insecurity commission this study? Probably! Do we care Not really!
NOT-SO-DUMB QUESTION OF THE MONTH
(Now, that’s a head-scratcher!)
Will an entire generation be deaf thanks to earbuds?
Jonah Pal, Arlington, TX
X “No, but we’ll see a number of people with hearing loss in the future,” says Abbey Berg, an audiologist at Pace University. “Kids listen too long at excessive levels. An hour a day at half volume is OK.” Pete Townshend agrees, saying maxing out headphones and concert amps have destroyed his eardrums. God, hope we die before we get old.
