What Tom Brady can do is use his celebrity and some opportunism to market multi-vitamins while insinuating they will protect you from Covid-19 or take advantage of the concussion issue in football to sell you coconut water mixed with tylenol. And he can take all the criticism that comes with, at best, suspect business practices and, at worst, dangerous misrepresentations of the medicinal properties of his bull####.
