The DRS stands for Drag Reduction System, which enables a car to open its rear wing to limit the downforces on the car. This increases the car's theoretical performance and in theory facilitates passing.
Sleep apnea facts. 1  Sleep apnea is defined as a reduction or cessation of breathing during sleep. 2  The three types of sleep apnea are central apnea, obstructive apnea, and a mixture of central and obstructive apnea.  Central sleep apnea is caused by a failure of the brain to activate the muscles of breathing during sleep.

There can be major hurdles to tolerating CPAP, and if you canât overcome these, you aren't totally out of luck.
