What I found out on Christmas Day 1984, through biochemical evidence, was that telomeres could be lengthened by the enzyme we called telomerase, which keeps the telomeres from wearing down. After I found that out, I went home and put on Bruce Springsteen's 'Born in the USA,' which was just out, and I danced and danced and danced.
