content: If it was just helping people fixing their computers and setting up their software,  but once you did it,  you now own any and all problems they’ll ever have in the future with the computer you fixed or the software you set up;  it never ends, you can’t get out of it.   Even ex-gfs will hunt you down years later to get you to fix whatever gadget they once nagged you into fixing. A wee bit younger than yourself, and with a less exciting career,  but same results. ...and I have also learned never to answer when asked which computer, or software, or mobile thingy to buy.  Same issue.
