If you ever find yourself in a conversation with Mark, whether it’s about such wide-ranging subjects as inventory management in the apparel business, the complexities of climate change, the challenges of keeping America’s coastlines safe, or even sailboat racing on the Great Lakes, it’d be a good idea to know what you’re talking about. Because this 67-year-old semi-retired product management expert sure does.

“One thing that I don’t like about certain people is that, frankly, they don’t know what they’re talking about,” he readily admits. “I have really dedicated myself to not talking about things I don’t know anything about. We could all do with listening more and talking less.”

Mark lives in the western New York State town of Hamlin just outside of Rochester, and about 80 feet from the shores of Lake Ontario, which, considering his involvement with the U.S. Coast Guard and his passion for a particular class of sailboat racing on big water, makes perfect sense.

Mark is an expert in the application of the technology of radio frequency identification (RFID) in the apparel industry, a high-ranking officer in the U.S. Coast Guard Auxiliary, and a championship racer of small catamaran sailboats. He also holds a graduate level certificate in sustainability from one of America’s leading universities, an accomplishment that he’s been able to use to deepen his understanding of the complexities and interrelationships of the world around us. Just as an example, he cites data about how the use of natural resources like water and cotton in the manufacture of a pair of blue jeans can affect the global climate.

He continues, “I was a product manager at stores in the apparel business involving the application of RFID technology for more efficient inventory management. RFID allows you to just walk along a rack of clothes and the technology scans all the tags as you’re walking by, so you can read many tags at one time, and you don’t have to actually see the tag that you’re scanning. What that means is that instead of taking two or three days of six people doing an inventory in the store, one person can probably do it in half a day.”

He adds, “I’ve been in the U.S. Coast Guard Auxiliary for 25 years and reached a leadership position of district captain. I also have a USCG Master Mariner license. I used to be editor of the Coast Guard Auxiliary magazine. For many years I’ve competed in a special class of small sailboat racing and have won championships at the national and state levels.”

A couple of years ago, Mark began to notice that his memory was starting to slip, as can happen with age. “Around the end of 2019 things just seemed cloudy. When I was younger, my memory was sharper.”

He began using Prevagen and soon saw improvement in his memory. “The difference between then and now is considerable,” he reports. “Does Prevagen work? Absolutely yes! I know this because every night before bed I play a number game on my computer. Since I started taking Prevagen, I think my cognitive functions have changed – for the better!”

And that’s from someone who prides himself on knowing what he’s talking about.
