Can Humans Smell Cancer?

Unexpected findings as a Scottish “super smeller” sniffs cancer. by Chris Gilbert, M.D., Ph.D.  “Did you have red Tabasco sauce with your last meal?”  Joy asked me as my husband and I were driving her from San Francisco to Chico, California. I was surprised by her question.  I did have red Tabasco sauce the night before, but not more that 4 drops.  How could Joy have smelt it? “Yes”, I said, “but it was such a minuscule amount”.  “I can smell it” she commented laughing. The 3-hour car trip from San Francisco to Chico, California was off to a good start.  Joy was definitely an … Continue reading Can Humans Smell Cancer?

Trim and Fit? You May Still Have Heart Disease

CreditCreditGracia Lam By Jane E. Brody Lessons from Jane Brody’s brother: Having all the right cholesterol numbers and staying active is no guarantee your coronary arteries are in great shape. This is the story of my brother’s coronary bypass surgery. It contains three critically important messages: 1. Don’t assume that your coronary arteries are in great shape because your “numbers” are good, you’re taking the prescribed medications to keep them that way, you’re trim and athletic and you live a mostly heart-healthy life. 2. Don’t ignore or dismiss potential symptoms of coronary distress by assuming that muscle soreness, unusual stress or … Continue reading Trim and Fit? You May Still Have Heart Disease

Do Dogs Forget Their People?

Illustration: Chelsea Beck (Gizmodo) by Daniel Kolitz Let’s say your long-term relationship totally implodes. Browsing for a new apartment, or a therapist that takes your insurance, you hear your dog bark in the other room—and realize, with a start, that it’s not actually your dog. Once you’re all moved out, the dog will be out of your life, too. Stewing in self-pity you think—and subsequently become convinced—that this dog, who you’ve fed and bathed who knows how many times, and coined several adorable nicknames for, will forget you ever existed by the start of next spring. Probably, for your own health, … Continue reading Do Dogs Forget Their People?

Here’s How Long Common Drugs Stay in Your Body

Just in case you were wondering. by ERIN BRODWIN, DRAGAN RADOVANOVIC Contrary to what many advertised drug tests might promise, not all substances leave their telltale chemical signature in the body for the same amount of time. The moment we take a drug – whether we snort, smoke, or swallow it – our bodies begin to break it down. In the process, metabolites, or byproducts, of the drug are produced, which can linger in our blood, urine (and even in our hair) for long after the initial effects of the drug are felt. Traces of these metabolites are what drug … Continue reading Here’s How Long Common Drugs Stay in Your Body

How Anxiety Dampens Sexual Pleasure

By Dr. Nagma V. Clark, Ph.D., L.P.C.C.  Occasional anxiety is a normal part of life and even expected or beneficial at certain times. It’s normal, for example, to feel anxious before a big test or a job interview, and some level of anxiety is needed to ensure that you are well-prepared. However, chronic or generalized anxiety is problematic because it keeps your body in the fight-or-flight mode, increasing the overall levels of stress. High levels of stress and persistent anxiety greatly reduce our ability to enjoy sex. An anxiety-ridden mind is in a constant state of heightened awareness, hyper-vigilant, and always … Continue reading How Anxiety Dampens Sexual Pleasure

Love, Death, and Other Forgotten Traditions

What we don’t tell our children. BY DORSA AMIR The science-fiction writer Robert Heinlein once wrote, “Each generation thinks it invented sex.” He was presumably referring to the pride each generation takes in defining its own sexual practices and ethics. But his comment hit the mark in another sense: Every generation has to reinvent sex because the previous generation did a lousy job of teaching it. In the United States, the conversations we have with our children about sex are often awkward, limited, and brimming with euphemism. At school, if kids are lucky enough to live in a state that … Continue reading Love, Death, and Other Forgotten Traditions
