You could ask silly questions about any type of cycling really. How do bent riders keep from getting run over every time they go out?
I consider myself a "roadie" as I ride on the road, but my handlebars and seat are level with one another. The only time I use the drops is going downhill and then it's just to get more aerodynamic and get some free speed. Most other times, I'm on the hoods and I have no issue with breathing. Don't have any issues with breathing in the drops either though.
