My son asked me about Spark Points the other day, he didn't understand why I would care if they didn't lead to some material gain - for him that would mean a new Lego set or maybe a video game. I had really never thought about Spark Points with any determination, but as I explained it to him it occured to me that:

Spark Points are important b/c they are a way to measure healthy choices. Tracking food, drinking water, exercising have all been proven to contribute to increased fitness. However, reading articles on fitness and nutrition, listening to a radio show, etc. also support a healthy lifestyle by increasing my awareness. Information is power! My favourite SP feature is that it gives us the information to help us achieve our goals and the tools for measuring our progress: it becomes cyclical as each positively impacts the other.

What I didn't share with my son is the strange smugness I feel when I reach a new level or achieve a trophy ;)
