National High Five Day

I know it's late in the day but there was a time when people relied on me to find the useless detritus of the internet for them. In honour of that I will let you know that where I am, there are about 5 hours left in National High Five Day. Now, it was started in the U.S. "National" implies it's just in the 'states but I think everyone can take some joy from the "high five". I hope you do.
