 You know, a lot of patients just like the idea better that it's less invasive. But I will say, you know, as far as DBS goes, if you are a younger patient with tremors, let's say in your 50s or 60s, and you have, you know, hopefully another 20 or 30 years to live, we do have better evidence that DBS works for a longer period of time than the focus ultrasound. I mean, right now, we have good published data that the ultrasound treatment works for about three-fourths of patients in a significant way at the five-year mark.
