I do not know whether Mandela wants this 94 year old's battle to continue like this. But, Dear Lord, when it is my time to pass, hopefully in my very old ages, please minimize the pain. Please let the passing be quicker than this and please give my loved ones the strength to respect my wishes and just let it be.
