...actually tried to commit suicide at 21. I drank furniture polish. I had no purpose in life, and I thought it was all over. I checked myself into an observation ward [in a hospital] for a while because I knew I was suicidal. I wanted to get some help. And I had an epiphany. I saw people who had profound emotional problems. These people were manic-depressives and paranoid schizophrenics. I looked around and said to myself, I don't have any problems. I realized all I was doing was being absurdly self-absorbed and giving in to self-pity...
...trigger for this turnaround, surprisingly enough, was vaccine research's most notable failure. In the 1980s, as the AIDS epidemic began to spread, scientists tried to fight it as they had polio and chickenpox--by crippling the virus and using it to train a patient's immune system to ward off the real infection. Nobody really understood how the process worked at the molecular level, but until AIDS came along, that didn't matter much...
...that's undoubtedly only the beginning. Just a decade ago, medical science despaired of ever finding vaccines that would be able to ward off illnesses like malaria and tuberculosis, which have plagued humanity for thousands of years, and AIDS, which looked as though it might turn out to be even deadlier than these ancient killers. The notion that this venerable disease-prevention strategy would prove effective against these and others seemed farfetched...
...disease. Many nuts, such as pecans and walnuts, also contain a phytochemical called ellagic acid. In preliminary laboratory studies, ellagic acid seemed to trigger a process known as apoptosis, in which cancer cells kill themselves. Nuts provide another benefit: they contain vitamin E, a potent antioxidant that may help ward off heart disease and cancer. The downside? At about 150 calories per ounce, they are a sure ticket to the fat farm. Eat them by the handful, not the bowlful...
...routinely added to flour. Folate not only prevents neural-tube defects in babies but also lowers blood levels of homocysteine, an amino acid that irritates blood vessels and is linked to heart disease. Just as impressive, spinach contains two phytochemicals, lutein and zeaxanthin, that seem to ward off macular degeneration, a leading cause of blindness. One cup of spinach contains just 41 calories and no fat, so you needn't worry about any unsightly bulges in your forearms or anywhere else. Don't like spinach? Try kale, Swiss chard or collard greens...
