Somewhat related is Betteridge's law of headlines:

> Any headline that ends in a question mark can be answered by the word no. It is based on the assumption that if the publishers were confident that the answer was yes, they would have presented it as an assertion; by presenting it as a question, they are not accountable for whether it is correct or not.

I like to swap out any of these maybe-headlines with the exact opposite. It may help us, or it may not.

From the article:

> Just five minutes of activity a day was estimated to potentially reduce blood pressure, while replacing sedentary behaviours with 20-27 minutes of exercise per day, including uphill walking, stair-climbing, running and cycling, was also estimated to lead to a clinically meaningful reduction in blood pressure.

Sounds like 5 minutes of exercise is where it has a statistically significant measurable impact in blood pressure, but 20-27 minutes is where it's a meaningful impact.
