When people want to know what to do if they’re short on time, I tell them this story. Although I’m almost sixty, I feel much younger, and if I could get Art Kramer to scan my brain, I’m sure it would look younger too. I’m doing everything I can to keep my prefrontal cortex, and everything it’s connected to, pumped up. I miss days, certainly, but I try not to miss two in a row.
