I enjoy excellent health and have no trouble keeping up physically with my 33-years-younger wife, including hiking in the mountains, nor do I have any trouble being a full-time partner in caregiving for our three children age 4 and under (including one whose first birthday is today), along with having a far more than full-time career as a writer and publisher. I am almost 68 years old and haven't eaten meat since 1976. Please tell me when I can expect the bad health effects to kick in.
