The recent report on pressure distribution in proton supports its similarity to macroscopic stable object.
This is valid for other particles and, surprisingly enough, for {\it photons}
The general properties of Generalized Parton Distributions and Generalized Distribution Amplitudes are discurssed.
There are indications that Extended Equivalence Principle wich was suggested earlier to explain the Anomalous Gravitomagnetic Moments of quarks and gluons
may be generalized to their pressures and shear forces. The latter may be studied in the {\it inclusive} hard processes of tensor polarized gluons.
