Everyone over the age of 21 ought to read Father Tom Ryan's book, Remember to Live! Persons finding themselves in the "sandwich generation" will learn ideas to better help them understand their parents; persons facing the addition of years will glean new and needed spiritual, physical and psychological insights.
This book truly resonates with anyone who thinks realistically beyond today, but it also gently prods those who don't have open, realistic minds about aging and the need to "do it well."
Tom Ryan is an excellent role model himself, but he also provides examples of others whose experiences are invaluable. If you hope to have only the best of futures, run, don't walk to get this book, and then reserve a comfortable corner to assimilate its ideas.
