Q44: Can all ESPers have the ability to jump, if under the right circumstances? If not, what makes Sigma, Phi, and ?/Kyle so special?

     Actually, in terms of setting, only a few number of ESPers can jump. And I can only say that they were born with these special powers.
     It’s the same as, why can Usain Bolt run 100 meters in 9.58 seconds?
     Of course it is a result of him undergoing intense training, but it doesn’t mean if everyone trains they can all run 100 m in 9.58 seconds either.
