Why Me?

Why is it that everytime I go to my gym class, the person who sets up next to me either does or has 1 of 3 things:

1. Has horrible B.O.

2. Farts the entire class

3. Ate something really stinky for lunch and burps it up all class

I don't understand it! It happens in the Pump class or the Yoga class I go to. All I'm asking for is for gym-goers to shower, take a Gas-X pill and eat a mint!
