If you throw some data at a clustering algorithm, the clustering algorithm is guaranteed to give you clusters back. So I'm not convinced about the results suggesting a precise pattern of rapid aging.

Sounds like something someone < 40 would say. To anyone over, I feel like this study is pretty obvious. I'm in my early 40's and whatever change this is, has been discussed multiple times with my peers, active lifestyle or not, wealth or not, married or not, physical career or not. Everything starts to feel a little harder, whether it's exercise, problem solving, memory, sleep, sex drive, appetite, fuckin everything. Things change in your late 30s, for sure.

All young people think they are special and age is just a number. The rest of the population knows that isn't true. Spare me your weight lifting 80 year old, or "my grandpa worked the farm til he was 90" stuff, we all know those are extreme outliers.

Turning 44 this year and none of this has hit me at all? Still staying up all night on weekends, working harder than I ever did (not more hours, though), feeling more motivated to take on both paid and unpaid work outside of my job. And my sex drive just as strong (and just as unfulfilled!) as in my 20s and 30s.

I'm turning 40 very soon and feel the same.

People also often tell me I look and seem younger than my age.

But I also prioritize sleeping 8 hours a night. Eating low carb. Regular exercise. Plus I have no kids. :-)
