However, the boss is not rewarded, for example, they are more likely to gain weight. Older adults prone to obesity Researchers at the University of Auckland in New Zealand found that among 13,000 pairs of sisters (derived from the Swedish birth registry), older siblings were born at a slightly lighter weight than their younger sisters at birth, but they are overweight at 25 years of age 30% more than the sister, the odds of suffering from obesity 40% higher than the sister. However, due to uncontrollable factors in the long years from birth to growth, researchers can not determine exactly
