Most lefties are really good at tasks with their "non-dominant" hand.

I'm "right handed," and can't do hardly anything as good as a "lefty." The only example was hitting golf balls. My dad had a left-handed set of golf clubs when I was a teenager, and hit balls extremely straight and long with those. Much straighter than later in life when I had a right handed set of clubs. No fade, no slice...straight as an arrow.

When I bought my first set of right handed clubs, I started with a slight fade, but after taking lessons, I turned that into a slice. Needless to say, it's been a very long time since I visited a golf course...lol
