go-go years, slow-go years, and no-go years. The idea is that when you’re first retired, you’re raring to have all those experiences you’ve been putting off until retirement, and you still (for the most part) have the health and energy to pursue those experiences. Those are your go-go years. Later on, typically in your seventies, you begin to slow down as you cross items off your bucket list and your health declines. And later still, in your eighties or beyond, you don’t have a whole lot of “go” left at all, no matter how much money you still have.
