no evidence to support that aspartame is the cause of increases in cancer.
    But, as with vaccines and autism, once the myth is out there, the truth is hard to swallow. People started to blame their headaches on aspartame, even though a randomized, double-blinded, placebo-controlled study showed that aspartame did not cause headaches in “aspartame sensitive” people. Others started to claim that sodas with aspartame were high in methanol. Analyses show that there is more methanol in a glass of tomato juice, or in fruits and vegetables, than in a diet soda. Another randomized double-blinded, placebo-controlled study (a great study!) showed that aspartame had no effect on mood, memory, behavior, EEG results, or physiology. And, finally, a prospective study of 285,079 men and 188,905 women ages fifty to seventy-one in the NIH-AARP Diet and Health Study could detect no effect of aspartame consumption on the development of blood or brain cancers.
    There’s just no evidence. In study after study, these artificial sweeteners have not been shown to be the health risks that many make them out to be. It’s a myth.

Bathroom
    The door handle is the dirtiest fixture in the bathroom
    One thing we hear all the time from friends and family is the lengths they will go not to touch things in the restroom. One of the most common strategies involves using a paper towel to open the bathroom door. People seem to be genuinely afraid of the door handle. Rachel recently heard a woman pushing a public bathroom door open with her elbow repeatedly say “touching the door handle in a bathroom will make you sick.” Once Rachel left the bathroom, she saw that same woman smoking. Hmm. That’s interesting.
    Let’s take a breather and think this through. It’s important to think about why we assume certain things are “dirty” or can harbor infection. In the case of the bathroom, it’s because we know something “dirty” occurs there. Picture a bathroom in your head. We bet you didn’t picture a sparkling clean room, shiny and bright. We bet you pictured a dark, dank, filthy room. But it’s important to remember that that’s your impression. It’s not necessarily based on fact.
    The truth is that the actual dirtiness of an object or place comes down to two factors: (1) how many people have touched it with dirty hands, and (2) how often it is cleaned. With respect to the door handle of the bathroom, we can’t vouch for (2), but we bet it’s more often than the door handle in your office. But here’s the thing, as for (1), the door handle in the bathroom is touched far more often by clean hands—they’ve just been washed—than dirty.
    In fact, the door handle seems to be one of the cleanest things in the bathroom. Don’t take our word for it; it’s been studied. Dr. Chuck Gerba, known also as “Dr. Germ,” has conducted a number of studies in this area. Someone had to, we guess. In one study, he found that toilet seats and door handles are the cleanest surfaces in public bathrooms. Amazing, but true! The bathroom floor was the dirtiest thing in the bathroom by a long shot, and often contained more than two million bacteria per square inch. So don’t put your purse or briefcase on the floor (which we bet lots of you do)!
    Faucets and sinks are also worse than the door handles or toilets. That’s because people don’t wash their hands before touching those. Again, this has been studied. It’s not our guess. Think back to those rules we mentioned before. Think about the many things that are touched by lots of dirty hands and never cleaned. Things like elevator buttons. Shopping carts. Money machine buttons. Supermarket self-serve checkout machines. Playground equipment. Hotel room remotes.
    Should we continue?
    We don’t say this to make you crazy. After all, many of you are touching these things all the time and will not get sick as a result.
    Air dryers will keep your hands cleaner than paper towels
