I want to hold your hand... Holding hands is not only an expression of affection among couples, but it also makes climbing easier and strengthens the immune system of young children. Doctor and multiple bestselling author Werner Bartens vividly and practically demonstrates what medicine and neuroscience have discovered about the effects of physical touch. Additionally, it provides access to buried feelings; this helps to reconnect with oneself and others. Touch is our first language - everyone speaks it, everyone understands it!.
