I understand the AARP suggestion and the reasons stated that the elderly population are at highest risk regarding Covid. One could therefore assume they would be interested in a non-prescription effective solution like Tollovid that has essentially no side effects regardless of dose.
However, in my own experience recommended Tollovid to a number of elderly people, all have rejected it because they weren't comfortable taking it unless their doctor prescribed it. If Todos did conduct marketing research and found similar results, they may have concluded the AARP advertising wouldn't be effective in driving sales. I suspect they did a study across all age groups and demographics and directed efforts based on that study. Shareholders don't have the details so we tend to second guess their actions.
Perhaps someone will ask Gerald if AARP advertising or the older population marketing research was conducted for Tollovid. I remember Gerald mentioning the younger target audience as the reasons driving their decision for engaging the social media personalities based on their number of followers.
