What has roots that nobody see...

Here is the final word on nutrition and health. It's a relief to know the truth after all those conflicting medical studies.
The Japanese eat very little fat and suffer fewer heart attacks than do the British or Americans.
The French eat a lot of fat and also suffer fewer heart attacks than the British or Americans.
The Japanese drink very little red wine and suffer fewer heart attacks than the British or Americans.
The Italians drink excessive amounts of red wine and also suffer fewer heart attacks than the British or Americans.
The Germans drink a lot of beer and eat lots of sausages and fats and suffer fewer heart attacks than the British or Americans.
CONCLUSION
Eat and drink what you like. Speaking English is apparently what kills you.
