BATTLE OF THE FREE RADICALS. Some antioxidants are produced by the body and some by plants, and so they can be derived from the diet. Their job is to combat free radicals â highly reactive molecules formed as a natural by-product of cellular activity.
Grip (tennis) In tennis, a grip is a way of holding the racquet in order to hit shots during a match. The three most commonly used conventional grips are: the Continental (or Chopper), the Eastern and the Western. Most players change grips during a match depending on what shot they are hitting.
A grip safety is a lever or other device located on the back of the handgunâs grip which must be depressed by the shooterâs hand, when naturally grasping the gun in a firing position, so the gun can fire. It is usually similar to a manual safety in its function, but is momentary.
