Unless you're my brother. He used to come up sweating everyday after playing video games. Mainly SSBM or something. I'm dead serious. He'd have sweat spots on his shirt and everything. o_o Plus, he smelled. But that's because he would get way overexcited and spaz about everything. He'd be jumping up and down for the entirety of his playing. I imagine he lost a lot of weight from that.
But that's a different story.
XD Anyway, I do have DDR. I got DDR MAX 2 last summer and I'm... fairly good. I'm like a mid to high standard level now... and I can survive most songs on heavy (although that doesn't mean I can do them very well). o_o
