I know these responses might be a bit different than the question you are asking, but they lead back to the deeper question about lifestyle / finances /longevity. Marry wisely. One of the biggest financial hits I took was a very costly divorce. Don't be afraid to move to lower cost areas. Maybe not today, but realize that you might need to at different points in life in order to maximize your savings. Realize that you might need to find a career niche or even a different career that value your age and experience. I did this and it's working well. Take good care of your body and mind so that you can continue to work. Live modestly. This isn't about whether you drink Starbucks every morning, but rather whether you use your money overall in the smartest way possible. If you live modestly, you can live on less, which means if you get to a point where you need to make career compromises you are in a position to do that. If you are in tech, consider going to work at blue chip firm that makes its money in tech. You'll have variety in your career and it is likely they will still be in business 10, 20, 30 years from now, ie: if part of your desire to work a long time also revolves around stability and the likelihood you won't lose your job in a merger, etc at an age where it would be hard to find a new job.
