New technologies that promise to extend life and decrease pain involve innovations that require extensive scientific research  Ttherefore, investment in such technologies is very risky, because innovations requiring extensive scientific research also require large amounts of capital but are unlikely to provide any financial return
Nonetheless, some people are willing to invest in these new technologies
When investments in new technologies that promise to extend life and decrease pain do provide financial return, they generally return many times the original investment, which is much more than the return on safer investments.
