      Yeah it sounds really obvious, until you realize they're figuring out the actual biochemical mechanism behind it. Stress also increases the chance of heart disease and cancer. P53 (or specifically its failure) is also involved in many cancers.

      It looks like useless research on the surface, for the lay person. But when you dig into it you realize that if you can map out the biochemical pathway, you can think about designing drugs to block certain parts of it - resulting in prolonged life or decreases tumor incidence, for example. Stuff like this actually is important.

      Why is this only useful if they can cure "diseases x,y,z"? Isn't aging the most debilitating disease of all? If it yields any insights into how we age, even those that don't lead directly to cures, there can still be much merit.

    I thought the president just got messages from the big corporations as to what decision to make.

    Common sense isn't science thought.
