Hi, my husband will be 50 in a few weeks but he hasn't felt good for several months. He looks bad he is 6'1 / 181 lbs but his face is sunk in he looks hollow eyed. He is very fatigued and doesn't feel like doing anything. His maternal grandfather died at 57 with colon cancer and I am worried about this. He had a colonoscopy years ago. He doesn't have much of an apetitie either. We have been going thru a stressful time, my Mother had a stroke and we have been taking care of her.
