One of my best friends is 5'7", 180lbs of pure muscle. I've seen him eat 4lbs. of hamburgers, 2 sleeves of buns, 30 slices of cheese, and a bottle of 1000 Island dressing at a BBQ one time. He eats candy, ice cream, and drinks a load of beer. He doesn't exercise, and is chiseled. The same with the rest of his family. I stare too hard at a gallon of ice cream and gain 5lbs. Staying at his house when I was in HS was murder on my system.
When you wish upon a falling star, your dreams can come true. Unless it's really a meteor hurtling to the Earth which will destroy all life. Then you're pretty much hosed no matter what you wish for. Unless it's death by meteorite.
