It is the secret we are all trying to unlock — how to live long and happy lives.

Science has found the key to success — for men, anyway.

In the United Kingdom, men in general are not expected to live as long as women — so maybe they need a little bit more help.

The average life expectancy for a man is 79, where women are expected to live to 82.

The reason for women outliving men is genetics, according to Medical Daily. Women have two X chromosomes, which provides them with a backup if a mutation occurs. However, men do not have that luxury — they only have one X chromosome to express all their genes.

Lifestyle factors can also impact how long a person will live.
