Herson Steven Leon Valdez, AKA Un Tal Arañita, first captured the attention of the audience in episode 1, titled ‘Bending the Rules’ of TLC’s ‘Most Extreme Humans.’ The Colombian native is living with a rare condition that leaves him with what is commonly described as “backward knees.” Since the condition has restricted his mobility, he has always faced difficulty in walking. On the show, he explained that as he gained weight, it put additional pressure on his legs, further restricting his ability to walk. Gradually, he began fearing that he might eventually lose his ability to walk, leading him to consult a doctor about undergoing surgery once again.
Herson Valdez Sought Medical Help as His Condition Progressively Worsened
Herson Steven Leon Valdez, also known as Un Tal Arañita, was born with a rare condition called congenital multiple arthrogryposis, which has caused his arms and legs to bend abnormally and made movement a constant challenge. As his weight increased, the pressure on his legs intensified, causing them to bend further. He began fearing that he would soon lose the ability to walk altogether. Throughout those difficult years, Herson’s girlfriend of 7 years remained by his side, supporting him unconditionally. As he began thinking about taking the next step in their relationship, he realized he needed to find out whether anything could be done to improve his condition.

Herson revealed that when he was a child, he had already gone through more than six surgeries. However, his last procedure had not produced the desired result, and his legs eventually returned to their previous position. He eventually met Dr. Miguel Galbán, a specialist in the reconstruction of congenital deformities. After examining him, the doctor discovered that he was walking by putting pressure on a dislocated knee and explained that the condition was worsening. The doctor further stated that Herson would need two surgeries. Initially, the prospect frightened him, but he ultimately agreed to undergo the procedures to move forward in his life rather than allowing his condition to continue deteriorating.

On the show, Yorelis accompanied him to the doctors’ appointments and helped care for him, showcasing how much Herson means to her.
Herson also revealed that he wanted to seek medical help not only because his condition was worsening but also because he hoped to take the next step in their relationship by proposing to Yorelis. With the help of his family, he arranged a memorable surprise when he went paragliding. When he landed after the activity, he finally popped the question, to which she happily said, “Yes.” Herson also considers his family as an integral part of his life.
