On the other hand, my life isn’t a double-blind randomised controlled study.

I can’t bifurcate n times and give half of the me’s one treatment and the other half of me’s no treatment, and I especially can’t do that without revealing to myself which group of me’s received the treatment, and which received no treatment or a placebo. Who even know motivates us.

Additionally, what works for some version of me, for example there was a me who was younger and fitter and more appealing to the ladies, may not work for the older version of me who is less young, relies on testosterone supplementation to not be a writhing crying mess on the floor, and hasn’t had a root in 18 months.

That’s why the practice of medicine has always been considered an art and a science.

There’s art in learning to apply the practice of medicine in an effective way.

Also, populations change over time. Older doctors will notice that decades ago every second person came in with problem x, but now the patients of a similar age and similar live experience now seem to be experiencing more y and less x.

The human condition, while at least somewhat consistent insofar as we’re still puzzled by some age old questions, is also a moving target.
