時間に敬意を表して Respect for life span
There seem to be various life spans on earth. Bacteria that have no concept of life span, Turritopsis jellyfish that rejuvenate, seaweed that lives for over 100,000 years, cedars that live for over 2,000 years, sharks that live for over 400 years, and sea chironomids that only live for one hour as adults. In tribute to life spans.
