 So I had this procedure or I was exposed to it in my training fellowship now, you know, eight years ago, nine years ago. And it's still as dramatic as it was back then as it is now, where you can imagine patients living with these tremors for years and years of their life, needing to find ways around even holding a drink and bringing it up to their mouth, like not being able to drink coffee at all, just sipping it through a straw, not being able to, you know, brush their teeth without holding both hands together.
