I had a similar thought, but then it says "high intensity" stair climbing, which is not how I would describe my climbing.

Then there's also this:

> Researchers also found that those who stopped climbing stairs daily during the study showed a 32% higher risk of cardiovascular disease compared to those who never reported climbing stairs.

So I guess if we ever move we're actually worse off in the long run

Careful about inferring causality here.

What kind of active person suddenly stops being active? You presumably don't want to be that kind of person... but the stopping isn't necessarily a causal factor of the cardiovascular events (and the initial "being active" seems still far less likely to be a causal factor).

I didn't read the paper (paywall) but just climbing five flights of stairs might count as high intensity compared to just walking on even land. It's of course not high intensity for a fit person or compared to doing burpees as fast as possible. But especially in an epidemiological study on common heart disease, the assumed base level is probably something less than that.
