There's already a lot of active research going on using the Crispr technology to fix diseases like Duchenne muscular dystrophy or cystic fibrosis or Huntington's disease. They're all diseases that have known genetic causes, and we now have the technology that can repair those mutations to provide, we hope, patients with a normal life.
I have felt so insecure about my body at times. I've been on every end of the spectrum. I felt like I was too skinny and wished I could be muscular. I've felt like I was chubby and wanted to be skinny. I think everybody suffers from body image issues. I might exude confidence sometimes, but I'm pretty insecure.
