Most people can't buy the products for staying younger for themselves. They need to look for them at the store, so they may think that they don't need to buy this products if they are going to stay the same age. However, if we are talking about a product that helps aging, which could be life extension or anti-aging products, the product itself needs to be more expensive than a few hundred dollars.
Some people are interested in using anti-aging products, so they want to buy the most expensive ones. However, they often want a lot of products in order to be able to see how the anti-aging products affect their aging process, and the cost of those products is too high for them. I am not trying to discourage people from purchasing the most expensive products. However, there are lots of people who don't have the money to buy all those expensive anti-aging products. If someone asks me if I recommend anti-aging products, I say, "You need to be prepared to pay a premium price. A few hundred dollars is not going to be enough." People want to stay the same age but want to live longer too. They want to look younger than their years and live to the best of their abilities.
