WebMD: my favorite website.
 

I freaking love WebMD. They know everything.

For example, I just felt some sort of weird flutter in my chest, looked it up, and diagnosed myself with a premature ventricular contraction (or PVC), the skipped heartbeat we all occasionally experience often related to stress, too much caffeine or nicotine, or too much exercise.

Makes sense; finals week, just finished another espresso. Thank you WebMD--for putting my mind at ease. Just. Thanks.
