Stealth IRL

1. First, get all of the pops and rumblies out of your body, like knee popping and digesting food and just stuff like that. Sitting down and rotating your ankle roughly helps and running for your knees. Also, waiting about two hours after eating helps keep from the rumblies.
2. Stretching is a major essential for this. If your not stretched than your legs will tire out faster.
3. For the day time, clothing color really isn't a big deal because every one can already see you, so don't overdo it and just use some basketball shorts and a t-shirt (fingerless gloves if you plan on climbing) and a pair of rubber soled shoes (I prefer boots).
4. When you sneak, you have to place your foot in the desired location. Then you must apply pressure on your foot and then finally putting the rest of your weight on it so you can proceed with the next step, rinse, lather, and repeat. You must either walk from the very back of your undersole of your heel to the toe or roll the outside of your foot from heel to toe or walk on the front half of your foot very slowly, kinda like walking tip toed, but with your foot a bit flatter. Later you can try to go faster.
5. For the day, stick behind stuff. You can't depend on camouflage or darkness for obvious reasons. Basically, in the day, hide and move, just that, hide and move.
6. For the night, wear dark, close to skin tight, clothing. If it is too tight than the elastics will stretch and make too noise. If you plan on someplace like a friends or someplace you 100% can't be seen (construction sight, eavesdropping, etc.), than wearing camouflage is alright.
7. Bandannas or headbands at night are recommended so that the sweat doesn't drip to your eyes.
8. Sneaking at night is just as difficult as in the day. Sight might be harder for the other person but people are naturally more alert at night and the humidity drops making sound more of a problem. I suggest sneaking on dirt without rocks, sand, concrete, or soft grass.
9. be sure too stay perfectly still when in your hiding spot a night. The reason is because when being persuaded most things at night don't move so moving will give you away

shouldnt this be changed from "Stealth" to "Stalker" IRL?

Too bad you don't get cloak of skill or cheat death.
