I can second this. I have started my own company (twice), worked for start ups, mid size companies and now large companies. I turned 50 this year and can tell you larger companies are where it is at as you age. It's forty hours a week with great benefits and mostly static responsibilities. They value your experience and have no issue with the fact that they are just a job. If there is a new skill I need they are happy to pay me to learn it. You don't work on the new and exciting stuff but as you get older you will find exciting is more tiring than it used to be.
