Hydrogen, oxygen and carbon make up about 99% of the average human. I'm going to cheat a little and leave out the other 1%, which is made up of trace elements (that is, stuff there's only a trace of in the body). Then, let's assume an average adult weighs 70 kilograms.
1 Bake the potatoes: You can bake the potatoes directly on the oven rack, or you can place them a few inches apart on a foil-lined baking sheet. 2  Bake the potatoes for 50 to 60 minutes.3  Flip them over every 20 minutes or so and check them for doneness by piercing them with a fork.

Method #1: Classic Baked Potato How-To. Rub a small amount of olive oil on your potatoes, then sprinkle generously with salt and pepper. (Some people even roll their potatoes in the salt, which is A-OK.) Place your potatoes on a baking sheet and bake in an oven preheated to 425Â°F for 30 to 45 minutes. Total time will vary based on oven type and potato size, but not quantity. Just make sure the potatoes are evenly spaced on your baking sheet and you could cook one or 8 per pan. If youâre using a convection oven, you should bake at 375Â°F for about 30 minutes before testing for doneness. Youâll know your potatoes are ready when the outside is slightly crisp and when you pierce the center with a sharp knife the flesh inside gives way easily. Pro tip: No need to wrap your potatoes in foil in this method.
