nicholas beach on wednesday lunchtime when he decided to go for a walk. a sighting was reported at pedi. he then failed to return. he didn't have his phone with him. what can science tell us about getting a better night's sleep? some people think of sleep as a luxury... michael mosley, who's 67, has been on our tv screens for more than two decades, talking about health and science. apparently, this is the easiest and most reliable way to find out. a presenter known for getting stuck in. i've got this list of the things that i'm allowed on my new diet. he would often focus on diet and exercise. he's a regular on the one show — last night's programme opened with the presenters sharing the feelings of many viewers... lots of us concerned to hear that our friend michael mosley has gone missing whilst on holiday in greece, and our thoughts are very much with his wife clare and the rest of his family at this worrying time. we hope for more positive news.
