10,000 steps a day? Or 7,000?
The Lancet has just published a report saying that it is not necessary to walk 10,000 steps a day and 7,000 is enough. The idea of 10,000 steps a day has always been wrong!
In East Asia, including China and Japan, the number 10,000 merely signifies "A lot!". When the Chinese say "May you live 10,000 years!" they do not really expect it of course. It just means "A long life to you!" It is the rough equivalent of hearing in English "I've told you a million time not to do that!" They haven't really as we know.
Many Asian counting systems use multiples of ten thousands whereas in the West we go from thousands then jump to millions.
We fell into a culture gap with fit bits, smart watches and pixel watches etc.
