ah that is sad, sorry to hear that, lost a customer to cancer last year, you can grow close to some customers, some of us do any way. lost my dad to it in may as well 
Sorry to hear your loss, can't imagine going through that. Getting older scares me sometimes.
older has nothing to do with it mate sadly, cancer with take anyone at any age if it wants to, I really feel for people like this as I know what they are going through.
I have had cancer a few times myself, in stomach and skin cancer
I lost my little neice to this at three years old a few years back, that was a very hard time for all the family watching hopeless as it ravaged her tiny little body then at the end hoping that she would let go (thats trurmatises me today with the guilt of wishing a baby to die), still brings tears to my eyes now, bless her.
I hope anyone that reads this and is or has gone through this all the luck in the world,
My advice for this would be to talk to someone/ anyone bottling it up is not a good.
I remember all the guys on here that helped me, I will never forget that and you all know who you are

Sad post this
