I have an app that scans my email and helps me build and strengthen relationships. It is meant primarily for maintaining business relationships, but I have it plugged in to my personal email to monitor communication on my personal network.
One of the prime things it does is let you know if you are losing touch with someone. That is based on whether you email them or not. Apparently I am losing touch with myself and I have weak relationship. This has been declining since 2017. The irony is that I am now more in touch with myself than I have ever been, and that has been increasing since 2017.
