takes a look back at Prof. Tom Johnson's revolutionary discovery that launched a new era in aging research.  It also brings us forward to the present day as Johnson, who still maintains an active, diverse research program, confronts a worrisome prognosis.  With characteristic humor and perspective, he offers insights, not only on the prospect of advancing human life span, but also on how to gracefully confront one's waning years.
