We've spent a lot of time lambasting the vanity industries in their "anti-aging" incarnation. Quite simply, no product sold on the market today can extend the healthy human life span. The level of fraud and adventurous marketing has caused great damage to legitimate anti-aging research over the years. However, there is a vanity industry that is doing good work on regenerative medicine: hair restoration and baldness cures. Here, the profits to be had have spurred a great deal of fundamental research into regenerative medicine and tissue engineering. This work will benefit us all as it percolates into other, more beneficial, attempts to regenerate the damage caused by aging and disease.
