Life expectancy at birth in Ireland is currently 78.4 years for men and 82.8 years for women. This has increased from 75 and 80 years for men and women respectively since 2002. Not only are people living longer in general (lifespan) but growing numbers of people are staying healthier for longer as well (health span). As I often say, adding not just years to their life but more life to their years.
In short, I believe you have two separate ages. Firstly, your age based on your date of birth - known as chronological age - and no one can change that!
