  Hi Sambo!
  
  I’ve found some specific changes in DNA that is linked to how long someone survives if they get lung cancer. Of course I don’t know for sure but it’s something that other scientists hopefully will investigate so we know more.
  
  Otherwise I am looking at how B vitamines can affect blood pressure in adults, I hope something interesting can come out there too!
