I've seen someone who lost one leg and used crutches as a child. He said he lost his leg to a landmine while fighting on the battlefield. His step forward seemed very difficult and worried about how he would live when he got older later. In the past, crutches and wheelchairs used to help these people, but nowadays leg prostheses have developed a lot, giving them more choice. The woman in the clip wore leg prostheses and was able to do most of her daily life by herself. I hope that many of these kinds of products are developed so that people with disabilities can enjoy everyday life without any inconvenience.
