I've survived both.
Both will slowly kill a man. At least I didn't have to pretend to love the cancer. It didn't nag me. It didn't scream at me. It didn't shit-talk me behind my back. It didn't act like a bitch to my family and friends. It didn't fill my house with useless shit. It didn't divorce me and try to take my kids and part of my pension.
That is all.
