The human heart beats roughly 100,000 times every day, pumping thousands of litres of blood.

Why it matters

The idea in context

The number is only approximate, because heart rate changes with sleep, stress, fitness and illness. Still, the scale is astonishing: a fist-sized pump quietly keeps blood, oxygen and heat moving every minute of your life.

İnsan kalbi her gün yaklaşık 100.000 kez atar ve binlerce litre kan pompalar.

Bu sayı yaklaşıktır; çünkü kalp hızı uykuya, strese, kondisyon durumuna ve hastalığa göre değişir. Yine de ölçek şaşırtıcıdır: yumruk büyüklüğünde bir pompa, hayatının her dakikasında kanı, oksijeni ve ısıyı sessizce dolaştırır.

WonderHistory

In 1948, Britain's NHS became one of the first systems anywhere to make healthcare free for every citizen — and redefined what people expect from a state.
