Please allow me to express my sincere condolences on your loss.  The Bible promises that there will be a resurrection right here on earth under peaceful and righteous conditions (see John 5:28-29 & Psalms 37:29).  At that time humans will have the prospect of enjoying perfect health, and they will never have to die again.  Please visit jw.org and click on Bible Teachings ?
