why does it seem like more and more people these days have medical problems?
I rarely see anyone that is what I would consider "normal" (i.e. Does not have a medical condition of some kind). Why is this happening these days? Is it because modern medicine has made it so people with medical conditions can live mostly-normal life spans (that people in the past would have died from)?

why are corruption, poor governance and low standards of living more prominent in sub-saharan africa than in any other region in the world?
Why are other parts of the world including but not limited to South America, Europe and Asia not as affected? Did earlier European intervention make them "grow up too fast"? Is it a cultural thing? Is it an issue of morals (greed, envy)? What are they doing wrong that the rest of the world seem not to be doing?...

why we can't we convert any object with mass into desired energy?
I recently read that 1kg of mass equates to 90 quadrillion joules, which is approximately the amount of energy consumed by the entire world in an hour.
