I used be a computer technician at a small town computer shop around 2008-2011. More than half of our customers were over 60.
Sometimes I needed to take some tech support calls, and sometimes I needed to make house calls to troubleshoot the folks issues.
Literally every support call started with “Why doesn’t the email work?” while the actual problem ranged from ISP issues, and modem faults, PC faults, Windows configuration errors, to dead monitors or a broken mouse. Literally any computer fault could be described as a failure to access their email.
