i was wondering he gets tired of going short distances,he can not keep up with kids his own age (it is hard to tell in school since there are only 2 other
kids in his class ) but I have seen younger
kids go more then he does, my question is if they were to put in a pacemaker and set it so his heart can't go above or below a number say 60-120 and keep his heart in a regular beating pattern can this give him more energy?
