I was watching a Vsauce video on youtube about being bored. Michael (the presenter) mentioned the Boredom Proneness Scale. It took the test and it concluded "You have a 0% chance of being bored out of your skull."
This sounds about right to me. The only times I can remember being bored are when I am recovering from illness. There is a feeling of 'I want to do something, anything, but I don't have enough brain power to work out what I could do." Occasionally, I can think of activities, but I don't have the strength, patience, or brain power to carry them out. I now have a little file on my computer desktop entitled 'Open when bored'. It has a number of ideas for beating boredom. I really do need constructive outlets, otherwise I am a danger to myself and others.
