Most common sense - however, youngesters need most

for education, for marriage, for housing, travelling, etc. etc. One cannot save for the sake of saving account and wait until 62 for spending. If one saves a million at 62 and dies at 72, does he expect spending $100k every year during the last 10 year while spending only 10% or 20% of income during his first 62 yrs of life?

A dollar at age of 22 worths much more than a dollar at age of 32, and much more than a dollar at age 62 even without considering inflation. One can do lots of things at 22 while can only do a little thing at 62. Life is very short. At age of 62, the best use of money is to donate.
