rewards? well i'm a poor man..working on the job for U$200-U$250 pay each month, i fold since January 2007, 24h/7d if i'm not out of town.
as far as i remember, I always must think 100 times before buying any hardware/software but i notice ever since i start folding, somehow i always find a way to buy/upgrade computer parts to continue my gaming hobby and almost never broke any hardware since my PC fold..maybe that's my rewards..
I'm not saying it's not worth solving, but with the overpopulation as it is now all those computers can probably research other things instead. Anything related to solving more structural problems. Being healthy is worthless when you have nowhere to live and nothing to eat.
In my great country we have a saying "dweilen met de kraan open", the literal translation is "mopping with the tap running". See if you can figure what it means and apply that here.
it's a little different problem..while we eat today, we always get hungry the next day, nothing is worthless..social, politic, health, environment problem will be solved on each track..compiled all tiny solved problem together we will get a better world.
