Lets assume a lot of your bones was screwed/plated/etc... together. And lets say they used a metal dense enough to affect a bullet's spin. It would be possible that a bullet bounces off one plate/screw, into another, into another as you spin causing it to be redirected enough times to be turned around and "ricocheted' at the terrorist. | ||

Such a series of impacts would also deform the bullet majorly, in a way that would then turn it from a nice, aerodynamic shape designed for maximum accuracy and range into an irregular lump of metal, thus affecting it's trajectory once it is flying through the air again by making it unpredictable and reducing the range even further. | ||

And now, lets compute at what speed your body would spontaneously combust. Temp for combustion T = 1255K, T_ex = 15C -> 288K. C_p = 1.004kJ/kg*K C_v = C_p - R = 0.717. Treat skin as an adiabatic surface, so using supersonic flow equations: 1255/288 = 1 + (gamma -1)/2 * M^2 Thus M (speed of sound = 4.1). c = sqrt(gamma*RT) -> c = 340m/s v = Mc -> 1394m/s Lets assume you contort yourself to your lowest inertia state along the perpendicular to the ground axis by putting yourself in the shape of a pencil. From your center of rotation, performing a self measurement, the outside of your arm would be 25cm away. --> r = 0.25 theta_dot = v/r angular velocity = 1394/0.25 =5576rad/s Times that by 60/2*pi to get rpm = 53,247RPM As 120000 > 53247, you will catch of fire before while performing this maneuver. So no it's not possible, don't know what these uneducated fucks were talking yapping on about here (lol jk). And don't even start me on showing how the forces needed to achieve such a speed in such a short amount of time go beyond the material limits of the human body. edit: And this of course assumes that the bullet is like a marble travelling through a straw which is rotated about 180 degrees. Realistically the insides of your body would not have high enough ultimate shear strengths to allow this to happen anyway. | ||

First one: you try to spin, so that the bullet goes back out. The bullet will go on roughly following its initial trajectory, but if you manage to turn 180° in time, it could get back out on its own momentum. A figure skater can get up to 6 turns per second, so we are talking about 1/12th of a second for the half turn. For a bullet travelling at 300m/s, this is enough time to travel 25m. So that can't happen. Second one: you hold a "U" shaped tube in front of you, that somehow receives the bullet and sends it back without friction, magically not slowing it down in the process. This still means you receive twice the kinetic energy of the bullet in the process, so you need to be ready for the impact to not be sent flying and hold the tube steady. The energy itself isn't huge (jogging into a brick wall), but better add a cushion for safety. | ||

You forgot option three, where you catch the bullet and beat the terrorist to death with it rolling high on improvised weapon. | ||

Eat a 100% French fry diet and you will then be a 100% gluten free vegan that is more obese than a 100% meat eating Eskimos. | ||

There are plenty of unhealthy non-meat products. Of course knowledge counts too. For instance twinkies have beef product in them. | ||

But even a vegan could manage. Sugar, cocoa powder, plant oil will all enable you to become as heavy as you desire if combined correctly. Plus, just eating a lot and not moving is a pretty sure way to get fat no matter what you eat exactly. | ||

Protein is one of the most important things you need in building muscle, and you can definitely get protein without meat. exactly you can get all the necessary amino acids without meat, but some will involve some pretty complicated planning, if you also want to reach certain macro targets (which is pretty common in body building) a good general rule is to mix beans and seeds with cauliflower (and the likes) you can play with this here: http://scoobysworkshop.com/protein-calculator/?GROUP=1100&NDB_NO=11135&GRAMS=50&calc=Y to get some idea how to complement your foodstuffs to meet all the requirements | ||

other factors of course include the role of intimacy and the symbolism of the act in your relation | ||
