Is it common to respond to these expensive health cons?

Doctors, mostly, not necessarily, sell pills for the purpose of “Live a Long, Healthy Life.” They come in a box of between five and eight bottles of capsules and run over $100 a set. They have videos about them on the internet you have to listen to forever before they announce the cost. You take a certain amount of each pill once or twice a day thinking you’ve located The Fountain of Youth. How effective do you think these pills are for longevity?
