How OCD are you?
If you find 2 bothersome, then you are 50% OCD. If you think 3 is making you lose your mind, then you are full blown 100% OCD.
OCD has been on the rise in the US since the beginning of the 21st century. Simply put, more people are either being diagnosed with OCD or are finally getting the treatment they need.
But OCD can also afflict people on varying levels. For some people, that can be quantified by the Higgs-Borshinger Test that helps quantify how OCD an individual is.
If you find 2 annoying, but 3 okay, then you should be on the lookout for overextending your OCD ways.
If 3 drives you nuts then you may want to go see a professional to give you help. The bigger the difference between circles the more a person is annoying equals more OCD.
