Two inherited DNA variants that can cut a person's lifespan by up to 3 years identified

Scientists have identified Scientists have identified DNA changes that can cut a person's lifespan by up to three years. They have discovered two separate areas of the human genome where differences in the DNA code may affect how long a person lives.
The two changes - known as variants - are relatively common in the population. More than two thirds of us will inherit a single copy of one of them from either our mother or father.
Having a copy of one variant may reduce expected lifetime by up to a year, the study found. Around three in 1000 people will inherit two copies of both variants and can expect to die an average of three years earlier, the team predicts.. These are relatively common and more than two thirds of us will inherit a single copy of one of them from either our mother or father.
