However there is a 2nd lesson to be learned here. Why in the world does he not have any savings at 64? The article is scant on details, but does mention he was in the computer industry from his 20s, and raised his son, say, until roughly his 40s. That leaves 20 prime years of earning power w/o savings? Something is amiss.
To me this is the lesson learned. If you're in the IT space, live way below your means. Most of us should be earning fantastic salaries and saving it for the day when the same industry that called us "Rock Stars" dumped us as fast as one leaving their 15 minutes (read: years) of fame.
