I read on a blog somewhere many years ago on how many days a person can live: 365 days in a year, a 20 year old expected to live around until 65 years will have remaining years to live of 65-20= 45 years so 45 years = 45 x 365 = 16,425 days left to live.
Now, 3 years = 3 x 365 = 1095 days. In 3 years, 1095 days are removed from your remaining time to live so that makes you think a lot about if I go to this event or do this or that, am I wasting my time/ am I moving towards my life goal(s) with the limited time I have/ am I drifting aimlessly/ do I hang out with the right type of people/ do I have to argue with a person/ do I have to endure a difficult situation etc.
