They are almost gone.
Some called them "the quiet generation," for they endured much and did not complain. Their children called them "the greatest"- perhaps in the hope that they could bask in the reflected glory.

Seventy years ago today, individual soldiers came a dime a dozen; they gave their lives by the thousands and with their own blood purchased freedom and prosperity for their nation.
Perhaps because of that hardship, they determined that their children should be protected from harm, sheltered from horror - and so we got the Baby Boomers.
