Richard Walker, BSc, PhD, is an editorial consultant and author of DK's Encyclopedia of the Human Body. He trained originally as a zoologist. Richard gained his PhD in physiology and biochemistry, and taught both secondary school and university students for a number of years before embarking on a successful career as a writer and consultant.‘Twenty-Four Hours a Day’ is a book of meditation, thought, and prayer that is soul inspiring, spiritually uplifting, and filled with sage words of wisdom. While geared toward members of Alcoholics Anonymous to help them in their daily program of recovery, the book has much to offer any individual who is working on self-improvement and personal growth, and who is searching for spiritual uplifting and guidance. The book is divided into the 365 days of the calendar year, offering a thought, meditation, and related short prayer on each day. Much of the material is based on the Big Book and other A.A. literature.
