IN: Is it true that can you sleep on a bed of nails?

A bed of nails is an oblong piece of wood, the size of a bed, with nails pointing upwards out of it. It appears to the spectator that anyone lying on this ''bed'' would be injured by the nails, but this is not so. Assuming the nails are numerous enough, the weight is distributed among them so that the pressure exerted by each nail is not enough to puncture the person's skin.

IN: Is it true that did dr hook ever get their picture on the cover of the rolling stone?

As the song was riding high on the charts, the magazine acquiesced to Dr. Hook's request -- sort of. The March 29, 1973 cover of Rolling Stone did indeed feature the band, but in caricature, rather than in a photograph. Also, the group's name was not used; instead the caption read simply, ''What's-Their-Names Make the Cover.''

IN: Is it true that is there a bridge over the panama canal?

The Bridge of the Americas (Spanish: Puente de las Americas; originally known as the Thatcher Ferry Bridge) is a road bridge in Panama, which spans the Pacific entrance to the Panama Canal. Designed by Sverdrup & Parcel, it was completed in 1962 at a cost of US$20 million, connecting the north and south American land masses. Two other bridges cross the canal: the Atlantic Bridge at the Gatun locks (expected 2018) and the Centennial Bridge.

IN: Is it true that is st andrews day a holiday in scotland?

The celebration of Saint Andrew as a national festival is thought to originate from the reign of Malcolm III (1034--1093). It was thought that ritual slaughter of animals associated with Samhain was moved to this date, so as to assure enough animals were kept alive for winter. But it is only in more recent times that 30 November has been given national holiday status.
