How we Spend our Days is How We Spend Our Lives
To begin, let's take a look at an average human life.
You will live to be 79 years old. That is 79 years to live and breathe and experience this earth. It is 28,835 days to see the stars and enjoy the sunlight or the cold or the ac. It is one lifetime to be spent however you see fit, but only one. Our bodies are one-time use, after all.
