Having a poor relationship with your family could make you sick

(CNN)It appears the quality of your relationships with your extended family -- mom, dad, siblings, aunts, uncles, grandparents and more --- could make a real difference in your health as you age, maybe even more than your special love.

A new study finds people who feel they aren't supported by their extended family are more likely to suffer chronic illness than those who aren't happy with their spouse or partner.

Who appreciates you?

The study, published Thursday in the Journal of Family Psychology, looked at data collected on nearly 3,000 people between 1995 and 2014. The average age of people was about 45 years old during the first round of data collection.
