My Monkey Sphere

I was reading this blog http://sentenceofdave.blogspot.com/ the other day and came across a new term, monkey sphere. Although, it is interesting I don't agree with it, but it did get me thinking too.
Monkey sphere: Aka: Dunbar's number: (A short definition) It is the supposed cognitive limit to the number of individuals with whom any one person can maintain stable social relationships: Most people put the at 150.
I was thinking of all the people in my monkey sphere and came up with the number 33. I guess that just means I have limited cognitive abilities.
