In a few weeks – May 22 to be exact – I will celebrate my 91st birthday.

I’m a lucky man, but I recognize a lot has changed for me in the past few decades.Twenty years ago, for example, I worked out with a trainer every morning. The goal was to be physically fit and, yes, help the body live as long as I could possibly push the envelope. But a stroke and a head injury later, I realize I could have been strengthening my brain capacity as well. Now recovering slowly, I’m all on that.

Supporting brain health research has been both a philanthropic mission and a physiological experience for me lately. In addition to donating to The University of Texas at Dallas’ Center for BrainHealth for educational and research initiatives, I’ve also been a participant in research projects.
