A few months ago, my father-in-law turned 80. As a gerontologist, I’m a big fan of celebrating major milestones when it comes to aging. But, for my father-in-law, I find this accomplishment more exceptional than usual. You see, we’ve suspected my father-in-law was a cat for years because he seems to have nine lives! Despite a barrage of serious healthsetbacks, and there have been some biggies, he always seems to bounce back.
