According to constitutional typologists, endomorphs tend to be round and soft, with protruding abdomens. They love gracious living and food. They have gentle, relaxed temperaments and prefer to keep life uncomplicated. Said to embody the cliche about fat people being friendly, endomorphs like to be surrounded by their friends and are not comfortable being alone for any length of time.

Thank you in advance for your help.
