​Luckily, with help from atmospherical oxygen and liquid water, the first multi-cellular organism was developed, and left its footprint after 2.7 Gyr the Earth formed [1][2]. Since that, life has constantly changed and diversely developed on this planet. Gongyi Shi, a newborn homo sapiens, opened his eyes in Tokyo, in 1998. This creature, like others, is carefully moving his step on the road of maturing and aging, towards death.
