Inconveniences

Further things that one can't do very easily with only one working hand/wrist, discovered over the past week:

• complete half-finished Fair Isle knitted jumper
  
• ride a bicycle
  
• put up an umbrella
  
• put a glove on the contracted hand
  
• knead bread
  
• write on a small slip of paper while holding it still with the other hand
  
• open sealed jam-jars
  
• press Ctrl-Alt-Delete on Windows...
