After I became more adapt eating with my left hand following breaking my wrist there in the mid '70's , I occasionally ate with both hands. It was just a few years ago after watching people eat that I realized that some people only use one hand to eat and drink with. Me I use whatever hand is closer to the cup or toast or what ever.

After my accident I even used chopsticks left handed and cracked eggs left handed one handed. Still, though, I usually use two hands to crack an egg. Unless I want shells in the mix or want a mangled egg

If we don't count our blessings
We are just wasting our time
