"It's not just x, it's y." Absolutely clear tell, especially at this frequency. Examples from the article below:

"Over decades, it doesn’t just wear down, it also starts to run hot." "... the therapy didn’t just clear brain fog, it physically improved the brain’s ability to process and store information."

The quotes as well: "'... Not just living longer, but living smarter and healthier,' Shetty said." "'We aren’t just trying to understand the biological mechanisms, we are translating and developing our findings into real-world therapies that could make a difference,' Shetty said."

What that is is a tell of bad writing
