1/ A US study recently concluded that drinking more water than just to quench your thirst was pointless, although not harmful.
I drink perhaps less than two litres of water a day. Less in winter, more in summer. I think a decent amount of water is needed to keep your liver and kidneys clean and to keep your skin and other organs hydrated. However, I have always thought it a bit odd that we are the only creatures who drink more water than just to quench our thirst.
2/ A Highriser study has concluded that wounds heal more quickly with a band aid over the wound.
When I was growing up, a band aid was needed to stop bleeding and protect a wound, but as soon as practical, the band aid would come off. Expose the wound to the air. It will heal more quickly, was the mantra. When I recently fell over, I kept the nastiest wound on my hand covered with a band aid for about a week. I am surprised how quickly it has healed. Even Dr Karl who was an 'expose it to the air' proponent has seen the light and believes wounds do heal more quickly with a band aid on.
