In university, we did programming exams on machines with no hard disks, which booted from DOS floppy disks. The teacher recommended at the beginning of the exam to save often, especially before running our programs, because if they got stuck, we would have to reboot, losing everything. Of course, there was still a guy that typed for a whole hour without saving. Upon running his program, it obviously crashed and he lost all his work. I got the habit of saving constantly pressing ctrl-s ever since. I do it even in apps that don't save anything, getting annoying sounds from my computer.
