This is a great topic to discuss! Woow  NAKED, BARE, SEXY hmmm!
Well anyways, Naked running or jogging is popular not only in America or to some European countries but also in Asia.  People run and run without wearing anything, some they cover their faces to avoid embarrassment or what so ever.  But you know what? They are enjoying the stupid activity they had.  

Is there a healthy result from running?  Big NO! It is very obvious.  Men wear protectors for their balls protected and women wear bras for their breasts.  So if you  remove all these protections and run? You know what will happen to you after you are done.   Well we might be asking ourselves why there are many people doing this shit?  The answer is very simple it is simply for FUN and tradition!

In most people in Europe they run naked because of their cultural heritage and beliefs, something that reminds them to run naked would improve their health or maybe success in the near future.  But for those who are watching - They have seen bunch of Assholes doing crazy stuff.

Funny huh, what is nice to see if all running naked are young, but if old?  You would wish you weren't there. 

In Asia and some parts of America some youth run for Fun! They are proud to show their sexes to everyone.  So proud even they have small penises tingling around their balls.  But doing these they have prove to all that they the guts to do crazy things like that.  Some think of it as a self-esteem booster and some thought of it as the solution of relieving desperation, loneliness and pain.

In Somerville they have this Quad Run, where students run naked or some wear mask or costumes. The Naked Quad Run usually takes place on a cold winter night, usually on alcohol. Students run from the back door of West Hall, around the Residential Quad, and return to West.

In the Philippines, Students who are members of a certain Fraternity, they have this so called oblation run (based from the Oblation in their school).  This is a traditional Fraternity activity in honor to their founder and here, they run run naked.  But now they don't run for that cost only, they run when they want to express their sentiments towards many issues in the Government and giving assistance and support.
