Approximately 600

I wondered how many calories a person can burn while swimming. Last night it felt like I burned a ton. Why is it that when we are out of breath doing an exercise we want to believe that we are just tearing through those unwanted calories we have accumulated throughout the day? As much as I would like to dream that last night I worked off the few small chocolate candies I ate mid afternoon, research says that in my 90 minutes in the pool I probably burned 600 calories. How many calories are in those small chocolate candies, you know the 1" x 1" milky way, 3 musketeers, snickers that you can get in the Halloween bags? I think ignorance is bliss when it comes to that answer and I'll just be happy with my 600 calories burned from swimming.
