People shower a lot. On average, every day. Scientists seem to think that the amount we need to shower is more like once or twice a week. I’m on the scientific end of the spectrum in winter, and more average in summer when it’s disgustingly hot here. My main problem with showers in winter is that eventually you have to get out of them.
So apparently daily showers are yet another thing we were convinced to do by advertisers, in order to sell more product.
I’ve noticed some recent discussion and news coverage of the idea of labeling foods with red, amber or green labels, based on how healthy they are. It’s known as the ‘traffic light’ system.
This isn’t actually a new idea. It was proposed in 2006 in the UK, but didn’t happen then because of objections from the processed food industry.
Studies had examined the effect of the traffic light labels on people’s eating, compared to US-style ‘recommended daily intake‘ labels.
