Death gives us purpose in life. With the fear of mortality, Man probably would not be doing most of the things that we see around us. He knows that his life on Earth is finite. Hence, there is a need for him to work hard as he wants to experience all the pleasures found here before his light burns out. Knowing that he has an expiry date, there is a need to produce progeny and care for his offspring, hoping that he will be cared for in old age.
