30 years ago, my mother passed away. 9, 7, 4, and 1 - that is how old us kids were. Brain aneurysm at 31. Not necessarily tobacco related, but she was a smoker.
Every one of her children has now outlived her, and my younger brothers have little to no memories of her. Hell, I barely have any memories of her.
Point being - life is too damn short, fragile, and can change in an instant. Dont waste what little time you have here with loved ones, including sneaking off to have a chew or staying on the toilet or going on unnecessary drives to the "store", etc. Enjoy and embrace that freedom.
