When newspapers give daily contradictory advice on how to live longer, and on what foods will either help you or kill you, how do we know who to trust and what to do to genuinely reach a ripe old age? Public Health Consultant David Conrad presents the evidence, interpreted through the amusing questions of Ariane Sherine.

If you're reading this, you probably want to live to a hundred.

And why wouldn't you want to live a super-long life, if you could remain in good health? You'd get to meet your great-grandkids, try out space travel and the teleporter, and gross out your descendants by having noisy old-person sex.

Comedian Ariane Sherine has always been determined to live into her hundreds, but never knew how. With so much confusing and conflicting health information out there, she didn't have a clue where to start until she met David Conrad, a public health expert, who helped her weigh up all the research and explained exactly what to do to live a long and healthy life.

And together, they've decided to tell you how to live to a hundred too.

This book has all the facts, stats, inappropriate jokes and shameless puns you could ever need to make it to your eleventh decade. Read all the evidence behind a hundred factors that affect life expectancy - everything from green tea to gardening and sex to sweeteners - and discover what lifestyle changes you should be making to live longer.

You'll also find funny and entertaining interviews with celebrities including Derren Brown, Clive Anderson, Charlie Brooker, Stewart Lee, Richard Osman, Lou Sanders, Jeremy Vine, Robert Llewellyn, Robin Ince, Josie Long, Konnie Huq and many more.
