People who do these kinds of things often live longer. It gives them a purpose in life. This is really stressing me. Join a hiking club or a certain sport if you enjoy these things. There are single travel groups.
Church sometimes offers opportunities.
Bars are definitely not the place to go. Giving out the vibes of urgency just gets you into trouble. Delegate responsibility and that takes effort. If your kids can help, dedicate part of the load to them and it will instill responsibility. You can hire someone to do some of the work if that is a possibility.
