TAURUS (April 20-May 20): How long do you want to live? Before you answer, remember that thousands of scientists are engaged in research to crack the code of the aging process. They will ultimately make breakthroughs that could allow you to be healthy and vigorous for many more decades. In the meantime, the astrological omens suggest this is a perfect moment to meditate on what you can personally do to promote your own longevity. What habits of mind and body can you cultivate that will keep you forever fresh? And now I drink a toast to your coffin, Taurus. May it be fashioned of lumber obtained from a hundred-year-old cypress tree whose seed will be planted this week.
