Physical Danger
The guy you advised to buy shares of HotNewCraze.com has a pretty nice set of golf clubs, and decides to make it a brain-basher night. You forget to lock your door, and all of a sudden this guy's got your right eye laying four in the laundry basket.
That's a pretty graphic example and, as it turns out, completely unnecessary, as this would never happen. So don't worry about it—you'll be fine. The worst that'll happen is that your high-stress career will start to take a toll on your body over time, or that you'll drink eight energy drinks in four hours and spend the next week sugared out of your mind.
