i had encephallitis at age 19. encephalitis effects the whole nervous system,because once u overcome the coma your nerves coat them selves with a coating to protect themselfs leaving your body numb all over. im constantly weak and im supposed to exercise to wake my body since my body is always asleep. alot of people die from this but some survive with different outcomes. i fought off the infection and im able to walk talk after relearnig both. after 20 years im still effected by this so it must be a god send that forces me to exercise. so think of all the negative thing that come with a sleeping sickness and overcome them through exercise bcuz you have been ordered by the powers above to exercise
