I thought it would be cool to hear other people's experiences with specific reality checks and how reliable they are.

Which reality check has been the most reliable for you?
The least reliable?
Which has given you an incorrect reading at least once?

For me:

Which reality check has been the most reliable for you? Digital watch checking. Nose plugging has been perfect too but I haven't tried it as much.
The least reliable? Looking at my hands. They look perfectly normal whenever I try.
Which has given you an incorrect reading at least once? Looking at my hands, and attempting to read.

You don't have to use this format by the way.
