I wrote an email to Bill Gates after reading his answer. I suggested that he should invest in anti-ageing research and/or cryonics. Ageing is a disease that afflicts everybody, and I think it would be a far better use of his money if he pledges financial support for anti-ageing research than if he continues pouring funding into curing malaria.

In addition, he has enough clout to motivate more people to take anti-ageing seriously instead of dismissing it as wishful thinking.
