After seeing a post about male swim suit technologies... I bet you are hesitant to click on the link now... don't worry there are no NSFW imagery of budgie smuggling... I thought it would be interesting to checkout the Swimming world records mentioned.

So for a tldr; It's an animated graphic illustrating the relationship between the introduction (and withdrawal by banning) of advances in the technology.
But its interesting that banning the all body suits in 2010 came at a great time for all the athletes who used them to set world records using them in the 2009. These records are pretty much set in stone for the time being...
