If you want to work into your 80s like Warren Buffett, you have some planning to do.
At the same time, Buffett acknowledged that he has no imminent plans to retire. Another 10 years at the company might be too much, he said on CNBC, "but every time I see one of my doctors, I just say, 'Guarantee me five more years.'"
Like Buffett, more aging individuals are aspiring to keep working in their golden years. Recent research from Gallup found that 63 percent of working adults plan to work part time beyond age 65, while 11 percent plan to continue working full time. That contrasts with current retirees, of whom 68 percent retired before age 65.
