I'm 49 now, and can't say a lot has changed in my career due to age. The only real change here is that with the job I accepted most recently, and where I've been for nigh on three years now, I don't do much coding anymore despite having a title of "Principal Engineer". A lot of what I do now is closer to management, even though I don't have any people reporting to me. Now in regards to life more broadly ... the big changes have mostly been around health & fitness. I was great up until about 42, and then things took a bit of a downward turn. I went from having no (known) chronic issues and mostly only needing the doctor for sports related injuries, to developing type 2 diabetes and eventually have two heart attacks. Luckily, despite all that I can still mountain bike, run, etc. but I'm definitely starting to notice that I don't have the energy I used to have. And now I'm on a pile of prescription drugs and see the doctor a lot more regularly. The biggest thing I'd say to someone who is right around 40 is this: if you're in good shape physically and are active, KEEP IT UP. If you're not very fit and aren't active physically, please for the love of FSM, find a way to get active and get fit. And when you do get there, don't stop. That was always one of my problems throughout my life: I'd go through "phases" that would alternate between me training for competitive sports and focusing on fitness to an obsessive degree, and periods where I was a complete slob / couch potato. Too many of the latter are, I strongly believe, a big part of why I saw the health decline I did. I hate to be the preachy type, but please take this to heart. Adopt a healthy diet, find a way to stay active, maintain your cardiovascular health, etc. It really is worth it, especially as you age.
