Men dies 5 years earlier than women

Do you know that a man dies 5 years earlier than a lady? If a man dies at age 78, the lady will die at the age of 83. Women can help men live longer by letting them eat healthy food, excercise daily. You must watch out for the food you eat, especially when you are old. When you are old, you will get ill easily, not a simple one but something like cancers.

I wonder why men dies so easily even they are careful of what they eat and are very sporty. This is what i read in the newspapers and i do not actually agree with them.
