I went on a diet a few years ago. I obsessively recorded every food I ate in MyFitnessPal. To this day, I know roughly how many calories pretty much everything I eat is. So, I've learned from the process and don't need the process as much any more. (I'm kidding about that - it's easy to underestimate how much you eat, and an extra 200 cal a day adds up over the years.)
I did something similar in my early 20’s. 15 years later the weight is gone and hasn’t come back. It is pretty nice being able to eyeball my plate of food at a BBQ knowing it will not add any flesh to my mid section.
I definitely did not need a multi-PB storage array to reach that goal. Or did I? I am sure someone out there knows roughly the human brain storage capacity in MB.
