Vague thought: it is very bad when important scientists die (in the general sense, including mathematicians and cmputer scientists). I recently learned that von Neumann died at age 54 of cancer. I think it's no exaggeration to say that von Neumann was one of the most influential scientists in history and that keeping him alive even 10 years more would have been of incredible benefit to humankind.

Seems like a problem worth solving. Proposed solution: create an organization which periodically offers grants to the most influential / important scientists (or maybe just the most influential / important people period), only instead of money they get a team of personal assistants who take care of their health and various unimportant things in their lives (e.g. paperwork). This team would work to maximize the health and happiness of the scientist so that they can live longer and do more science. Thoughts?
