A solid high five requires skill, patience and supreme hand-eye coordination from both parties involved.
The sad fact is that every single day, at least 76%* of high-fivers worldwide are receiving half-assed, awkward or completely missed high fives. (*probably) These poor celebrators are left hanging all by their embarrassed lonesome, with no one to five -- high or low.
