HOW’s this for an idea which could prove to be a money-spinner for someone? A stopwatch which cannot be reset to zero, but which can be switched on and off under different headings like a computer or mobile phone.

Over time, it could record accumulative periods spent on different activities, which could prove invaluable to a person’s lifestyle. It could record how many minutes/hours/days/months/years of valuable lifetime are being spent on some activities, when there are so many other activities which could be enjoyed with that time.

For example, for males – particularly in retirement – it could record the collective time they spend in a lifeless condition outside fashion stores and ladies’ toilets.

All suggestions welcome, but no offence intended, ladies. Wife Sylvia has become quite aggressive.
