I surf in my spare time.
that's really awesome! I always wanted to know how to ride the wave! Surfing looks like so much fun

Do you have to be standing to ride a wave, or can you surf lying down on the board?
refers to the act of riding a wave with a board, regardless of the stance used. There are several types of boards. The native peoples of the Pacific, for instance, surfed waves on alaia, paipo, and other such craft, and did so on their belly and knees. The modern-day definition of surfing, however, most often refers to a surfer riding a wave standing up on a surfboard; this is also referred to as stand-up surfing.
Another prominent form of surfing is body

If I can get another 10 or 15 years of surfing - that's fine. I've worked hard, I tell myself, as I'm throwing the board in the car. I owe it to myself. A bit of water over the gills. That's my reward. I'm happier
