Ex-Beatle Sir Paul McCartney has picked up a strange new exercise routine - eye yoga.
The singer, 66, discovered the technique on a trip to India last year (08).
In an interview on U.S. TV, the musician demonstrated his odd new workout, during which he stares in different directions and holds his gaze for 20 seconds at a time.
He was taught the routine by an eye yoga expert at a hotel in India.
MCCartney says, "He told me eyes are muscles (and) are just like any other muscles, and they need exercise to keep them working properly.
"Spending so much time at computers or (watching) the TV or reading books, we are only using one set of muscles in our eyes. The yoga gives a workout to the other ones."
The singer claims he indulges in an eye workout up to six times a day.
