Gilberg = the greatest.
Great tip about the eyes. I actually can do that with my nostrils when trying to smell two different smells at the same time, but not with my eyes. The key is to dab a line of vaseline on the line that separates them and that traps any molecules that could interfere with the nostrils working independently of each other. Unfortunately, it's not useful for golf, but it works great when trying to decide what to eat for lunch at a mall food court.
Oddly enough though, I do have a piece of big toe bone from an ancient man (carbon dated to only 30,000 years though ) and I tried to use that, but I think I scratched my cornea. It's actually not a total loss though because I was right eye dominant and now while it's healing, my left eye is getting much stronger. Ask your friend if this is normal progress for learning this.
Also, lastly, someone here needs to pat Wally on the head and explain to him what's going on.
I figured I'd just ignore the "trolling" of Gilberg as he was obviously doing that here. Heck, his picture is a troll. I figured I'd add something of some value to the thread so it's not another semi-pointless thread.
