I've been enjoying building calculators with ChatGPT to help me model various life decisions.When my friend shared he drinks 1-2 Starbucks Mochas per day, it made me wonder how that impacts his health over the course of the year (or several years).Drinking 2 mocha's per day adds 45.9 lb (20.8kg) body fat that your body either needs to burn or store per year.
