I've begun to work with sterile cultures in a biosafety cabinet. That means that everything is washed with water and 70% ethanol before and after I work, that I must organize my work surface so that at no point my hands pass over an open container or its cap, and that my homework consists of picking up a plastic tube cap 3 cm wide and 1 cm deep with my index and middle fingers and manipulating it until it is screwed back on the tube.
Without, of course, having my hand over any inside part at any point.
Strangely enough, I picked up the skill on the first try, while my lab partner had to try several times and with her left hand before succeeding. After some experimentation, I have become increasingly certain of a hypothesis I formulated some time ago: I am extremely right-dominant.
My right hand is very dexterous, while my left is slightly clumsy. I can stir or whisk something in the kitchen much longer when using my right arm over my left. I can carry a bag longer if it is on my right shoulder than if it is on my left. I can make some faces with the right side of my face but not the left, raise my right eyebrow, and my right hand is always more mobile than the left when I type. The only exception I can find is that I balance or spin on my left foot and stumble and stagger when I attempt either on my right foot.
I don't know what that means, other than that the brain is fascinating. Hopefully I might know why by the end of this semester, once I have read all of my Neurobiology book.

I find manual dexterity and left and right dominance fascinating too although I am never likely to read about it nor understand it. I do, however, wonder how my son can operate all four extremities independently and left and right with almost equal dexterity (which is why he was able to sit down and play the drums without practice and become an accomplished ROV pilot). On the other hand I am very right-dominant and have little ability to operate my two sides independently without a great deal of practice.
