Europeans. No wonder they have so few children, their all - well - you figure it out.
The tiny Swiss canton of Appenzell Innerrhoden has voted to prohibit the phenomenon of naked hiking.
Anyone found wandering the Alps wearing nothing but a sturdy pair of hiking boots will now be fined.
Appenzell is considered one of the most conservative regions of Switzerland; it gave women the vote only in 1990.
Locals have been outraged by an apparent upsurge in hikers who think the best way to appreciate the mountains is with their clothes off.
The vote was taken with a show of hands at Appenzell's annual Landsgemeinde, an open-air meeting of all registered voters held in the town square.
Appenzell is one of only two Swiss cantons that still decide local government policy in this way.
There was a big majority in favour of prohibiting naked hiking, and introducing fines of Sfr 200 ($175).
