0:25.2	save it and an AI device that gives a voice to the voiceless.
0:30.3	Let's get started.
0:31.6	Researchers at the University of California Davis have made a groundbreaking discovery that could redefine our understanding of aging and cognitive health.
0:39.0	Turns out, our brains are getting bigger.
0:41.0	Wow, okay.
0:43.0	I have questions.
0:44.7	Are you saying that as we age our brains are growing?
0:49.8	Okay, well, no.
0:51.3	So let's talk about the study because it's actually one of the most incredible things about the whole story.
0:55.6	Back in 1948, researchers in Massachusetts established the Framingham Heart Study. It was a longitudinal study aimed at uncovering patterns in cardiovascular and other diseases.
