So much of life's richness comes from dealing with the present, tackling difficulties, pushing through fears and allowing people into our hearts. A virtual hug is a sentiment only. Feeling someone's arms around you is a tactile experience, reality, fulfilling something deep inside the human psyche that cannot be replicated or synthesised.
We were made to be herd animals - a pack, for support and safety, shared joys and fun. When we withdraw physically from our own, we deprive ourselves of what we need, at the deepest level.
Conversely, when all our senses are engaged we are truly in the moment, truly living. Sweating as you tackle that mountain/climbing wall, feeling the water surround your body as you glide through, tasting the wind as you ride a bicycle down a steep road, watching your child play...
There is no substitute for what you experience physically, mentally and spiritually by actually being in the moment.
