But, yesterday, my left eye started twitching. And I started thinking about all the times in recent years when I got weird, random twitches. Sometimes an eye, sometimes my fingers, sometimes a quad. And then I thought about a very dear friend of mine who managed to have an eye twitch for weeks because of stress at work. And every time this friend gets the smallest of twitches - we always joke about work stress. Here's what Wikipedia says about physiological twitches:
·
Muscle contraction
and relaxation
o
Convulsion, rapid and repeated muscle contraction
and relaxation, resulting in uncontrolled shaking
o
Fasciculation, a small, local, involuntary muscle
contraction
o
Myoclonic twitch, a jerk usually caused by sudden
muscle contractions
o
Myokymia, a continuous, involuntary muscle twitch
that affects the muscles of the face, particularly the eyelids
o
Spasm,
a sudden, involuntary contraction of a muscle, group of muscles, hollow organ,
or orifice
o
Tic,
an involuntary, repetitive, nonrhythmic movement or vocalization of sudden
onset and involving discrete muscle groups
o
Tremor, an involuntary, repetitive, somewhat rhythmic, muscle
contraction and relaxation
Anyway. That's what my brain decided to talk about today. Nothing of real substance. Nothing that really has anything to do with anything. :)
