To be considered “Middle-Aged” today means to be between the ages of about 45-65. I’m 37, and I’m hoping that I never make it to middle age. “Middle-Aged” is a moving target, with the target moving faster and faster as health care technologies emerge and converge, and life expectancy increases. A few centuries ago, I doubt that anyone would consider a 60-year-old middle-aged, and it’s not unreasonable to think that a 50-year-old today could still be considered middle-aged in 50 years at age 100. At some point, maybe technology will be advancing so rapidly that we’ll abandon the label altogether.

For now, I’m going to continue enjoying my eternal “youth,” but I wouldn’t put it past my 45-year-old self to start riding around in a self-driving convertible – even if I’m not technically “middle-aged.”
