We have observed many times that electrons and photons choose the best way amoung different ways. In fact, their motions aren't by chance or equal probability. Even, some experiments like Young's Double slit experiments and water memory could be described by the clever behaviors of electrons and photons. We can go ahead and suppose that these particles are alive. We need to redefine the concept of life. Life isnt limited to respiration or having brain and heart or even DNA. But, signatures of life could be seen by analyzing the behavior of objects. Particles like electrons could understand and response. Thus, maybe, one regard them as alive creature. If we accept this assumption, then, we can use of it in curing diseases and many other applications in biology, physics, industry and et al.
