This sci-fi technology really helps my dad feel safer walking outside now

My dad loves walking outside, but his knees aren't what they used to be. Especially when going downhill or down the stairs, he feels struggling. So I got him a wearable exoskeletons(designed for hikers tho), but it's really been amazing. It has a resistance mode that slows him down on slopes and adds stability. He feels like a robotman in movies, moving more easily. He likes it very much. I'm just glad about this.
