 Question: can you have a heart attack from laughing Context: In the English and British tradition, the royal prerogative of mercy is one of the historic royal prerogatives of the British monarch, by which he or she can grant pardons (informally known as a royal pardon) to convicted persons. The royal prerogative of mercy was originally used to permit the monarch to withdraw, or provide alternatives to death sentences; the alternative of penal transportation to ``partes abroade'' has been used since at least 1617. It is now used to change any sentence or penalty. A royal pardon does not itself overturn a conviction.

These types of cheese are currently legally sold if aged for 60 days or more. Over this period, the salt and acid characteristics of aging cheese generally eliminate the growth of pathogenic bacteria.

The technique has been used heavily in many fields to remove a background from the subject of a photo or video -- particularly the newscasting, motion picture and videogame industries. A color range in the foreground footage is made transparent, allowing separately filmed background footage or a static image to be inserted into the scene. The chroma keying technique is commonly used in video production and post-production. This technique is also referred to as color keying, colour-separation overlay (CSO; primarily by the BBC), or by various terms for specific color-related variants such as green screen, and blue screen -- chroma keying can be done with backgrounds of any color that are uniform and distinct, but green and blue backgrounds are more commonly used because they differ most distinctly in hue from most human skin colors. No part of the subject being filmed or photographed may duplicate the color used as the backing.
