Titi monkeys are monogamous animals (having only one mating partner), mating for life. They are found in South America and live in family groups which consist of parents and their offspring (usually 3 to 7 members), and sit with their tails entwined. After a gestation period of about 5 months, the female bears a single young monkey. The bond between the male and the infant is very strong and the father cares for the young, carrying it and bringing it to the mother only for nursing.

Obesity isn't caused by diet alone - when combined with decreased physical activity, that is when it contributes to the weight gain epidemic and personal health problems.
