Here is another paragraph with my summary:
Though such people are jumpy, they like to keep their energy and don't fancy moving around much. They would rather sit quietly be themselves and keep out of difficulties. Trouble upsets them, and they run away from it. Their friends don't understand them very well. They move jerkily and feel jerkily. The psychiatrist who understands how easily they become anxious is often able to help them get along better in the sociable and aggressive world of endomorphs and mesomorphs.
SUMMARY
People that are jumpy don’t have a lot of energy. They ae quiet and stay out of trouble. Friends do not know what to think of them. They become easy agitated. A doctor can help them to socialize better in the world of today.
Is this ok.
