Be careful how you spend your bullets..!!!
When God send you into this world, it is like a soldier sent into
battle, and you are given and can carry only a limited supply to
last through your good years.
What is the average life span of a Man's good years - starting at
12 years old ?
The oldest man that is able to procreate was known to be at 80
years old, and is from a mountain area, with good clean air, frugal
life style, and without modern amenities (including
temptations).
He probably led a reasonable life without EXCESSES - which explains
his ability to have enough bullets left to score at 80 years of
age.
