Make do and mend?

As my mum has reached the point in old age that she finds buying anything new challenging I thought instead of buying a new one I'd just try to fix her old Panasonic upright vacuum cleaner which seemed to have given up the ghost.  Here's what I discovered.  The rubber band that drives the beater bar had snapped.  Easily replaceable spare part still widely available.  The bag full indicator button spring had worn out. Solution - manually check that bag isn't full.  The filters needed a bit of a clean.  New bag, brief filter wash, new rubber band ... almost as good as new.  After all, it's an entirely mechanical machine with a motor and no circuit boards so should probably last forever if properly maintained (or at least until the motor magnets give in).  It made me think long and hard about our consumer throw away society.  How many repairable hoovers are thrown away each year for no good reason?  That was my first reaction.  It's broken.  Throw it away.  Lazy.  Make do and mend...?
