Thanks again all.
My wife made an appointment yesterday to see the doctor.  Today she said she may cancel it because if she did have it, she didn't want to know.
Her mother died from it after a long drawn out battle.  She wasted away.
Her sister Penny, other than a swollen leg and a cough, lived normally right up till the moment she laid down to rest and passed away.
Stuff like this really makes you think.  Penny's husband has been retired about a year and they were planning their travels.  Now she's gone.  And he's never done much for himself, she did all the cooking and housework.  He's going to be lost without her.
Live is short, hug your loved ones and don't take them for granted.
