Lots of good advice, especially for younger people for whom it can pay increasing dividends because they're starting earlier. I have a small quibble about the idea of knowing when you're thirsty. Many people either don't realize when they need to drink more, or actively avoid drinking because they don't want to have to go to the bathroom more frequently. As a result, they are underhydrated and their overall health suffers. (This is largely based on my observations, not any studies, but it was confirmed to me by a PT who encourages people to hydrate more.) So while it may not be necessary to set a timer and drink a liter of water every couple of hours, simply thinking "I'm in touch with my body and I don't feel thirsty" may be a product of deluded wishful thinking. Also she mentioned around the 50 minute mark that "brain games" don't actually help you get better at anything except those brain games, but doing activities you like such as reading are helpful overall. What makes one mental activity more helpful than another? Most programmers tend to like brain games, so you'd figure any mental exercises are better than none, especially if you do different ones.
