passion is contagious Passion leads to a sense of purpose. Without a sense of purpose, we humans become untethered rather quickly. It’s why undirected retirement doesn’t work out so well for many people. What does one do if one feels lacking in passion? Passion is contagious. It is the antidote for...

the live-forever breakfast smoothie OK, no one is going to live forever (Sorry Ray Kurzweil, it’s a delusion). But it’s nice to aim for a long, functional, engaged life. Last week we discussed the dangers of glycemic loads, which are multiple. Then, what to eat for breakfast? Below is the...
