It always surprises me that people seem to forget that is to the human connection, communication and understanding. Take a moment and read the article in the link greatergood.berkeley.edu/article/item/hands_on_research
You might be surprised what you have been missing out on. Touch can help release, heal, communicate, bond, calm, balance and grow....And when i say touch, it can be as simple as a pat on the back, a handshake, a simple friendly embrace, a hug (or ideally 5 in a day), holding hands, a simple caress of compassion or love... Seriously, put a smile on and give it a try next time you are meeting someone, be it your boss or colleagues, your loved ones, a friend or even a stranger . You will notice the energy, the attention and the dynamic of your interaction will be completly different (in a good way, if done with clear good intention). And if you dont feel comfortable trying it in your surroundings, go try a professional, whether it's a massage therapist, a physio, an osteo, or the acupuncturist (amongst the many many therapies available involving some kind of touch).
Touch is simple, free and accessible and feels great, add some love and healing to your life through touch, even if its from you to you.
And for those that feel real adventurous, there are plenty of elderly that live alone and don't connect with anyone for days and sometimes even weeks. Get at it and offer a quick visit as a volunteer at a hospice or hospital and see how it'll brighten your day as much as it will brighten theirs.
