Yael Adler, an expert in combating age-related changes, wrote a book about how to preserve freshness and youth for many years. She offers practical advice for everyday life and argues that age-related changes can be controlled. The book presents facts about the aging process, such as daily loss of brain cells, the influence of moles on telomeres, and the dulling of sensitivity to certain tastes as you age. The author also warns against taking food supplements, claiming they are more likely to shorten life than to extend it.
