I did in fact buy and read the “Grow Taller 4 Idiots” book (160 pages). This following review is based on my actual thoughts on the program – not a fake write up. I go into digesting this program with a skeptical eye. If this can work, why won’t everyone grow taller? For myself, I’m already 6’0? tall, in my 50’s and don’t have a real need to gain more inches. I have however decided to follow Darwin’s system and try it out. I can’t hurt myself in any way. I’m planning to grow a few inches and become taller than my tallest boy at 6’1?. My family will be shocked! The height increase is permanent and will last the rest of your life. You must do the program in it’s entirety to get the maximum benefit and height increase. A step by step approach to the exercises is provided. He lays out what is the very best exercise to boost your height. Darwin gives you the exact recipe for the homemade cocktail for growth (pg. 29 ). This is amazingly simple to make.
