We are taught early in life that heart muscle repairs itself very slowly. You probably worried that it will wear out one day. So you determine to look after your primary pump by eating carefully and taking suitable exercise. You do what you can to keep the pipes clean and flexible so that your heart can pump some 8000 litres of blood around your body each and every day for whatever term you consider to be your life expectancy. That life expectancy in Ireland was 79.6 years for men and 83.4 for women according to the CSO in 2017.
