It's strange what we take for granted. I can't remember a time when I turned the tap and water didn't come out. More recently, when I've travelled, the water in most hotels has been safe to drink. So I find it shocking that we could soon be in a situation where we might have more smart phones than access to running water.

However, I ask you this question. Which would you rather do: Fetch your water from the end of your road, or give up your smart phone? And how many of you would quite happily buy bottled water via your favourite supermarket app and arrange for it to be delivered (whilst also knowing how many loyalty points you are collecting)?

Smart Phone v Running Water.

Which would you choose?
