I just finished a conference in Arizona where a Doctor did a presentation titled "THE BIOMEDICAL EPOCH". Here he spoke about so many fascinating developments in curing various diseases and how we are living much longer.  Specifically he spoke about DNA and how they are not only splitting, but reversing the structure of DNA.  Because of this I thought I would offer the attached video on DNA.

Three minutes is a short time to explore a subject where most doctorates only scratch the surface, so writer Andrew S. Walsh teamed up with molecular biologist Dr Matthew Adams to distil the script down to the most fundamental elements required to understand not only DNA's form and function but how our understanding of these discoveries has affected the wider world. While this length may feel restrictive, the team found that this limitation acted as a lens, focusing the piece on the essentials.
