Q. Hello Fitzy. I need your help! I'm six feet tall and last year I was close to 300 pounds. I am now down to 250. I'm still in the process of losing weight but am stressed because I cannot get rid of my "man boobs."They're devastatingly embarrassing. I wouldn't take my shirt off at the beach if you paid me. What can I do to make them go away? Liam

A. Hi Liam. Isn't it funny how big boobs are super cool on a chic but not so much on a guy? Interesting. Listen, I feel for you. Man boobs are not the status symbol of the day, and it's hard for most people to deal with any unusual bulging pockets of fat. Man boobs, love handles, and saddles bags; nobody wants 'em!

A few years ago, I helped my (female) friend move. Moving is one of those jobs that tends to be delegated to men by default, but I figured we could handle it. After all, we're a couple of strong, independent chicks. And the whole thing went pretty smoothly -- until it came time to life the large TV onto the high dresser. I could not lift it above my head, no matter what. The lack of strength I had in my shoulders was painfully evident.

Shoulders are an oft forgotten part of the body, but they're just as important as the bigger muscle groups--working on them will not only increase your strength but help prevent injury too. Here are some exercises that will tone your shoulders, making them sleek, sexy and best of all, strong:

Researchers have discovered a fountain of youth, in a manner of speaking, for the fruit fly. At first you're probably thinking why on earth would we want longer living flies? The good news is that the researchers were able to extend the lifespan of fruit flies by modifying only one genetic protein, which means inhibiting the aging process in humans may be much simpler than previously thought.

Fruit flies with the modified gene saw 1/3 longer lifespans with no apparent side-effects (although measuring side-effects in a fruit fly can't be easy or very accurate), so if the same were true for humans we could all theoretically live to around the 110-120 yr old range regularly.

Cool or scary? A little of both, I think.
