It is a healthy quote by Markus Herz!
Be careful about reading health books. Some fine day you’ll die of a misprint.
Things is even today and maybe even more so today we read health books or look up health issues on the internet, but how safe is it. Nine out of ten time we end up with a horrible looking death in the eye disease, while it is nothing more than a fart blocking you ass.
How is possible such old quote would still apply today.
