Gone are the days when we can afford to luxuriate under a hot shower for hours on end. Well, maybe the showers weren’t quite that long but most people are used to taking showers in the tens of minutes ...

We used to have a 2-minute timer in the shower when I was young. If you went past that mum or dad would shut off the hot water. Now it's in the 3-5 minute range, but I still try to keep it short.
