More than 20 different highly speculative theories of aging are now being tested in scientific laboratories round the world. The method or methods by which the human life-span will be extended depend on which of these theories turns out to be correct. Some of them have to do with genetic engineering-attempts to alter the program of the cell by changing the coding on the DNA molecule. But nongenetic theories will probably pay off sooner. One current favorite holds that aging occurs because certain giant molecules in human cells eventually get bound together. These immobile aggregations clog the cells...
...free radical" theory of aging, if proved correct, would probably lead to a simpler method of rejuvenation. Free radicals are fragments of molecules with a high electrical charge-which by their oxidizing properties can cause changes in the body such as hardening of the arteries. An antioxidant, which can be produced cheaply and taken in pills, is supposed to deactivate the free radicals, thereby retarding the aging process. One such antioxidant, BHT, has already dramatically increased the life-span of mice...
...President has special reason to be pleased. By 1972, if his advisers are correct, inflation will be under control, national output will again be growing at about its optimum rate of 41% yearly, and unemployment will be down. That would create an auspicious climate for Nixon's re-election campaign...
...SUSPECT that he is far too correct. The university has a way of offering an artist room and board in exchange for the sale of his soul, and corrupting his product with its ivory tower approach. In C and Echoi are fine musical exercises. As works for performance, however, they don't measure...
...correct answer is C, a fact that is sure to dumbfound anyone who visited the museum-like Château de Thoiry prior to 1967-or before the historic building became the center of what must be the most unusual animal farm in the Western world...
