I've never understood the fad myself. I rarely go buy the stuff. My filters in my kitchen are fine and my water tastes pretty good. This just gives me more reason not to get caught up in the trend.
It costs 10,000 times more to create the bottled version than it does to produce tap water, say scientists. Huge resources are needed to draw it from the ground, add largely irrelevant minerals, and package and distribute it - sometimes half-way around the world.
The plastic bottles it comes in take 1,000 years to biodegrade, and in industrialised countries, bottled water is no more pure and healthy than what comes out of the tap.
The second story is that the government in the UK is going to start making STD tests available for free. Good for them. It's a progressive approach to the problem.
