Our life is determined by our heart.
In reality as well as symbolically. When we love someone, we lose our heart to that person. When we are courageous, we stand up for something with all our heart. But when we are frightened, our hearts may well be in our boots now and then.
The heart is of central importance just as it is in the centre of our body. It is a masterpiece of nature in design and function.
It reliably beats 60 to 70 times per minute while pumping about six litres of blood through our body. And the heart can quickly and effectively increase this performance to up to 30 litres per minute under conditions of physical effort.
And when the heart does not work properly, it can be life-threatening.
