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.
replyI'm turning 40 very soon and feel the same.
replyPeople 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. :-)
