Perhaps it is more accurate to ask about "physical distancing", especially since forms of self-isolation such as working from home are playing a significant role in increasing social interaction between people via e-media. For example, I find myself answering more questions than ever here on ResearchGate.net . Stay safe!

I agree and your answer strokes well with my view on health status variations over time (in particular in chronic diseases) that might be better monitored analyzing patients by his/her variations in habits as customer, social media use, netflix choices, etc. This is also close to the suicide algorithm prediction facebook developed (https://about.fb.com/news/2018/09/inside-feed-suicide-prevention-and-ai/) for what its worth.

Keep the spirit high and reflect on what is important in life

The critical issue here is the balance of individual location privacy vs. public health common good. The latter takes precedence over the former during major public health emergencies and pandemics. In Israel, for example, they had to invoke emergency spy powers (https://www.bbc.co.uk/news/technology-51930681) to develop their COVID-19 HaMagen app (https://www.standardmedia.co.ke/article/2001365512/israel-launches-app-alerting-users-of-exposure-to-coronavirus). In Canada, Toronto is using cellphone location data from telecoms to encourage social distancing (https://nationalpost.com/technology/city-of-toronto-gathering-cellphone-location-data-from-telecoms-in-bid-to-slow-spread-of-covid-19-tory/wcm/f916f892-b47d-43a4-85aa-2a214e136ee0). Other countries are doing the same/developing similar apps; see some relevant news links at http://healthcybermap.org/WHO_COVID19/#10
