Q:

What does it mean when your eye twitches?

A:

Eye twitching may be linked to caffeine, stress, alcohol or fatigue, according to WebMD. The twitching is the result of an involuntary movement in the eyelid, occurring as often as every few seconds to several minutes apart.

Regardless of their cause, these rapid movements of the eye are harmless and typically go away on their own.

In more severe cases, the spasms may be a sign of a brain or nerve disorder or a specific eye condition, explains WebMD, including pinkeye, light sensitivity, Bell's palsy, Parkinson's disease and Tourette syndrome.

Eye twitching can also be a side effect of medications used for sufferers of epilepsy or psychosis.

  • Q:

    How many shots are in a pint of alcohol?

    A:

    While some bartenders pour with a heavier hand, a standard shot is about 1.5 fluid ounces or about 44.5 milliliters, and an imperial pint is about 19 fluid ounces or 568 milliliters, meaning that there are about 12.5 shots per imperial pint. However, the imperial pint differs in size from the U.S. pint, which is about 16 ounces or 473 milliliters, meaning there are about 10.5 shots in a U.S. pint. Another factor in play other than the exact size of the shot and the type of pint being used is the concentration of alcohol in the beverage; pints are typically reserved for diluted liquor drinks, including cocktails, or for lower alcohol beverages such as beer.
