A "Toned" Appearance Has Nothing To Do With Muscle Tone

Walk into any weight room, and you're almost guaranteed to see two things: a man straining to lift the heaviest weight he can, and a woman lifting a weight so light she doesn't break a sweat. This comes from the idea that lifting a heavy weight a handful of times will make your muscles big and bulky (something many men want but many women don't), and lifting a light weight numerous times will make your muscles long, lean, and toned (something many women want but many men don't).

How Alonzo Clemons Overcame A Brain Injury To Become A World-Class Sculptor

You've probably dabbled with Play-Doh as a kid. Most people's sculpting experience ends around there, but that wasn't the case for Alonzo Clemons. Severely disabled as a young child, Clemons could barely speak, nor could he feed himself or tie his own shoes. But his disability brought on one important gift—acquired savant syndrome, a condition where high-level, often prodigious skills appear after a brain injury. This gave Clemons an uncanny ability to create hyper-accurate sculptures of animals that started from a young age and only sharpened as he grew up. Today, he can simply glance at a horse on TV and, in just 20 minutes, sculpt a clay figure of that horse that is anatomically correct down to every muscle. Despite his still very limited vocabulary, Clemons has shown his work throughout the world. Hear Clemons speak about his work in the video below.

Having your hair washed professionally can be a luxurious treat—the best part of getting your haircut, even. Who doesn't like a great head and neck massage? But when your stylist forgets to prop your head up with a towel or two, it can be painful. Your neck falls backwards and the sink digs into your skin. Ouch. As it turns out, this position isn't only uncomfortable, it can also prove dangerous.As Peter Gloviczki, M.D., a vascular surgeon at the Mayo Clinic in Rochester, Minnesota, told Self, "beauty parlor stroke syndrome is caused when there is an injury, tear, or blood clot in one of the four major arteries that go to the brain." If your neck isn't properly supported while your stylist shampoos your hair, it can be hyperextended, and that can compress one of those four major arteries. According to Gloviczki, a tear in the blood vessel could result "in a blood clot, which can travel to your brain and cause a stroke." This syndrome, officially called iatrogenic vertebral artery injury, is rare, but it has happened.

But before you cancel your holiday beach trip for fear of a JAWS-style attack times two, know that the likelihood of a two-headed shark birth is 0.13 percent, and if the shark actually survives, its life will almost surely be brief.
