A little warning, I might get a little ranty on this. It’s sad to see people in my profession ignore common health issues and completely neglect our bodies. It isn’t good now and it becomes even worse later on when you’re retired.
Programming might be life but at the same time, it isn’t everything (or shouldn’t be). You’ve only got one life and you need to take care of your body. One of the biggest issues with us poor saps who sit in front of a monitor all day is the dreaded computer gut you get from weak core muscles. Simply put, when you stand up, if your belt buckle points to the floor, you’ve got some exercises to do.
Of course, I suggest you do more: get a gym membership, start working out (and don’t stop going after February!), trade your cokes in for a glass of water, and eat healthier. As engineers and programmers we spend so much time improving our brains we completely ignore our health. It’s time to stop doing that — become a healthy person your brain will thank you for it.
