I used to fix everything except electronic equipment. Even rewired and rebuilt my house without outside help.
I could set up my AC unit to come on automatically 30 minutes before I got home. It was easy!
Now the most simple tool or appliance seems to have an electronic touchpad that automatically defaults to the OFF position when no power is on.
I taught myself how to sweat copper pipe one day. The next day I began replacing the entire plumbing system in my house.
I recently added a basement room and needed to move a duct. On e I got started, it was pretty straightforward.
On the flip side, a guy from India once hired my brother to come attach a hose to a spigot.
