The 80 kg mass will cause huge pain, cutting flesh, breaking  joints, and above all pressing the toes extremely hard.

Give us some actual evidence that this should happen instead of merely claiming that it should happen.
He can't.
Because I'm an example of it not doing.

So, as usual, there doesn't seem to be a problem to solve.
There is a difference between putting a load on toes tips, putting the load on toes, and and putting it on feet balls . A human can stand on toes tips, toes , or a compilation of toes and feet balls  .I can stand on my toes only with ease. But if the person on the link put the loads on toes only  " and without wearing shoes " they will break joints.
Quote from: Bored chemist on 27/01/2020 19:05:18
Ballet dancers stand on the toes, but they have reinforced shoes to support them.
Of course they need shoes to stand on toes tips since the force I suggested is small but not zero also giving in consideration the toes tips are sensitive

Are you aware that rock climbers are able to support themselves using just their fingers?

Can you do that ? but every person can stand on toes.

I can't.  I put almost all my weight on the edge of the ball of my foot and I use my toes for balance.  My toes are flat on the floor.

I do not believe I could stand on my toes like a ballet dancer without shoes and not break my toes.

Why I have been neglected ?
« Reply #25 on: 20/08/2020 21:05:47 »
Why I have been neglected by discovering this new phenomenon ,These are obvious observations to prove that the force lifting human body  is less than the force lifting another object with the same mass:

An average  person can lift his body of 60 kg holding a bar many times but he will barely move a rock of the same mass 60 kg.

I can jump high raising my massive 57 kg  using only my thigh's muscles however I will not be able to even move a rock of 57 kg using all my body muscles.

A person can walk upside down on his weak arms lifting his 60 kg " average weight "massive body but he will not even be able to put the rock on his shoulders.

I'm merging this with the thread you made earlier about the exact same thing.

You were not "neglected". We put quite a lot of effort into showing that you were wrong.
You are still wrong.

My new great discovery can be tested to verify its validity ,so universities shouldn't neglect this great new discovery. and take it seriously.
Beside my logical observations above that shows small force can lift a massive human body here is an experiment to verify this in which only 17 kg force can lift my massive body of 57 kg , if my muscles force will lift another mass"not a human " it should use force  greater  than 57 kg.

Your assertion breaks the laws of physics, so it cannot be correct.

Looking at your video, it looks like your leg is applying a force at a slight angle to the force gauge. In order to get an accurate estimate, you'd need to have your leg and the force gauge perfectly aligned.

It is true and this is supported by obvious observations and a test.
What I discovered is an exception for a human body mass.It doesn't "break" the laws of physics ,it is a new law of physics .

Yes , the work against gravity appears to be smaller than the work exerted by mass downwards but this is only according to work being force times distance, but here the work exerted against gravity is the energy of a human being  .The idea of work being force times distance doesn't work here , the work here is the energy of a person .This is also a new physics law.
In the video by raising my body I will exert work greater than 17 times distance and equal to 57 times distance even though the work appears to be only 17 times distance.

OK, so you don't know what "energy" means

The whole idea makes no sense.
"The unique normal force on human body: a massive human can stand on weak toes"
Toes are not weak.

You need to start by explaining what  you are doing in the video.

No, it isn't.

There are no obvious observations in support of it. If you were talking about "observations" like this:

Quote from: Yahya A.Sharif on 20/08/2020 21:05:47
An average  person can lift his body of 60 kg holding a bar many times but he will barely move a rock of the same mass 60 kg.

Then you are, as usual, ignoring the fact that lifting a 60 kilogram rock is equivalent to your legs lifting 120 kilograms total, because your body weight doesn't magically disappear just because you're holding something heavy. Of course it's harder to walk while carrying a 60 kilogram rock than it is to carry a 60 kilogram body because your legs are bearing twice the weight in the first scenario than they are in the second. You honestly can't tell me that you don't understand that.

and a test.

Your test was flawed, as I pointed out earlier. In addition to the angling problem I mentioned, there's another one as well. It only took 17 kilograms of force for you to full extend your foot under the restraint of that force gauge. That is not the same as saying that your foot can only exert 17 kilograms of force. You were unable to apply any more force to the gauge because your foot was already full extended.

It absolutely does break the laws of physics because you could use that exact same principle to create net energy thus violate conservation of energy. The less force it takes to lift something against gravity, the less energy is used in the act of lifting it. In normal, law-obeying circumstances, the amount of energy that an object releases when it falls from a given height is exactly equal to the amount of energy required to lift it to that same height. If you introduce a mechanism that requires less energy to lift it to that height than you get from dropping it, then you get excess energy during the drop. The energy doesn't balance.

If we consider for example the force to lift a mass is usual but what actually decrease is the mass ,For instance if the mass is 60 kg let's treated it as a 15 kg one . If a person lifts his body he will need small force of 15 kg .If a person try to lift another rock of 60 kg he will need greater force one is his body 15 kg and the other one is the rock 60 kg a total of  75 kg  lifting a mass is absolutely greater than lifting a body "15 kg vs 75 kg " your example is only 120 half  which will not gives noticeable results  but the observation is very noticeable. "15 vs 75"

Are you aware what a 60 kg mass is ? it is 10 kg times 6 , you can obviously hard to hold and walk  with your 10 kg suitcase .

Do you not understand that the body is built in such a way that the 60Kg or so of your mass is well supported and held directly above your feet- symmetrically balanced.
But a suitcase is off to one side?

No
Mass is a conserved quantity.
There's an explanation / proof here.

Are you aware that, if you arrange things so the load can be lifted properly it's easy to lift twice your bodyweight and some people do rather more.
You should be, because I pointed it out a while ago.
But you seem to be ignoring it.

You have absolutely zero evidence for this, whereas there is very strong evidence against it (I posted how it can be used to violate conservation of energy).

Bored Chemist explained it. Balance has a lot to do with it (plus the fact that your legs are now lifting 70 kilograms instead of the 60 kilogram weight of your body alone). You should also find that it is your arms that are getting tired and not your legs when you carry something like that.

I use less than the maximum 17 kg to raise my 57 kg weight.
So why do you ignore this?

No, If 15  kg raises 60 kg, there is a scientific explanation in which the idea 15 kg lifting 60 kg agrees with the law of conservation of energy.The idea is force vs force not work vs work
