Aha! So you can test the OP's theory by repeating the experiment with nylon socks and no shirt. That's proper science.

If you die, I promise BC and I will report the result to Yahya's conference as confirmation of his hypothesis, and you will qualify for a posthumous Darwin award. Just get your brother to post the photos and death certificate here.
I guarantee that Kryptid will not die but if he puts bricks of 71 kg I will sue Bored Chemist for Kryptid death because that is his idea.

71 kilograms of bricks or 71 kilograms of human being doesn't make any difference as long as the contact area is the same. You get the same pressure either way.

Placing 71 kg concrete blocks on an area of 0.08 x 0.2 x 2 m (the area of two feet) on abdomen is fatal.

How is "0.02x 0.2x 0.2m" an area? In real science/math it is a volume. How about 71kg of feathers resting on one's abdomen, would that be fatal? PS: is Kryptid still alive or did that experiment terminate him?

I'm not dead. The specific material is irrelevant. Only mass and contact area is.

Forget about the physics of weight, area, and pressure for a moment, because you are misunderstanding the concept in this context. My question is: what is your opinion on placing 71 kg of concrete blocks on an area of only 0.032 m^2 (approximate area of two feet) of the abdomen? Do you truly believe that is as safe as the experiment you conducted?

If you are a fit adult male and prepared, supporting 71kg on .04 m2 of your abdomen for a short while should be no problem. Ask any rugby player.

For sure, for a short time. Kryptid has already done the experiment and I take his word that it was not fatal. We recommend that you do not sleep with the 71kg of concrete blocks on your abdomen.

Why specifically a fit adult or a rugby player or being prepared?Any individual can lie on abdomen safely even a child can lie on their abdomen over a small cylinder. But can any person safely place 71 kg of blocks on an area of just 0.032 m^2 without risking serious injury?

Kryptid did not place a 71 kg inanimate object, such as concrete blocks, on a small area of just 0.032 m^2.

There is a clear difference between an individual supporting their own body weight-60 kg, 70 kg-and the reverse scenario of placing the same mass in the form of rocks or other inanimate objects on the body. Kryptid clearly chose the safer approach, one that people are accustomed to, such as others standing on them. However, placing 71 kg directly on someone's abdomen is another matter entirely-I wouldn't even consider attempting it and posting it here. That would be sheer insanity.

So you agree it would be fatal? The reverse has been proven by Kryptid and others to be harmless.

No sane person would place 71 kg of concrete blocks on such a small area-you know it, I know it, everyone knows it.

You are just being illogical now. Nobody would want 71kg pressing on their abdomen but for the sake of the experiment Kryptid has done it and he is still alive, or so he says. 71kg of concrete blocks or a 71kg human both using the same contact area will be identical in effect. If you cannot understand this your grasp of basic physics is defective.

I bet no one would dare place five 15-kg concrete blocks on an area of 0.2x0.2 m^2 even for a millisecond. This isn't about physics-it's about risking one's life.

If I had them, I would. Would something else work as an acceptable substitute for you? Bricks? Metal? Barbel weights? I'll investigate what I have available.

Yes, any concrete or metal can serve as a suitable substitute. I was able to lie on my abdomen on a concrete block, supporting my full body weight of 63 kg on an area of just 0.04 m^2, for one minute without any pain-and I can comfortably maintain this position for even longer periods.
