Jack LaLanne lived to a ripe old age by eating well, and strength training. His book Live Young Forever shows the lifestyle of someone devoted to health and fitness, while enjoying a full life.
There is nothing really new in this book, but it does reinforce the principles you need to follow to stay healthy and strong.
At 90+ he was still at it working out on his regimen daily. Too bad he didn't make 100, but that is only a another milestone for someone who had many.
If you want to be inspired read his book. His juicers are a good item to own too, I personally have juiced vegetables for over 40 years and enjoy the healthy benefits you get.
