If you've ever watched the show My Strange Addiction, you know that people can eat some crazy things. But in the case of 6-year-old Zach Tahir, he actually can't help but eat strange, often inedible items. Tahir suffers from a condition called pica that causes cravings for non-food items.
Recently, Tahir's cravings had been getting out of control and his mom, Rachel Horn, had to do something about it. When he began gnawing through the walls and eating the blinds in his room she paid top dollar to have an inedible bedroom constructed.
That wasn't enough: One of Tahir's favorite activities was spending time in their backyard. But because he would search for things to eat (apparently moss is a favorite and he's been known to eat rocks), Horn began to worry about the area—and her son's safety. Through a charity event, she raised enough money to build a whole new backyard area—specifically, one that Tahir couldn't eat.
If you're beginning to think, "What are the odds that a child has this disorder?" they're actually pretty high. Between 10 and 30 percent of children between 1 and 6 have it, and it's especially common in kids with developmental disorders, reports the Daily Mail.
