A few colleagues and I discussed the importance of human contact not too long ago. Physical touch is the first sense we acquire and distinguishes us from animals. Touch has been scientifically proven to improve trust, decrease violence, improve emotional intimacy, improve learning, general wellbeing etc etc. Physical touch is the foundational element of human development and culture. In a litigious society growing with digital media it may unintentionally affect these factors negatively. All the science convincingly suggests that we are wired to, we need to, connect on a basic physical level. If we deny ourselves of that we are depriving ourselves of one the greatest important comforts. Old people are especially vulnerable to loneliness and social isolation and miss basic human contact which can have a serious affect on their health. I've always been very tactile with my grandma but am making a conscious effort to be more so.
