We have our jokes about old age about the bus pass etc. and even about dying. One ex-army Colonel quipped, "I get up each morning and if I'm not mentioned in The Times obituary column, I go back to bed!"
Most elderly people I know have a grand sense of humour, but it's not funny to lose one's partner, nor to suffer handicap and illness. These things can make a great difference in later years. One of my friends said, “I treat the hill from the station with respect these days". Very wise too.
We should not fight our limitations, but accept them gracefully. Tasks once done with ease can become tiresome. The eyes a little dimmer, and the hearing a little harder. The hand not quite so steady. And when these things begin to happen to a once active individual there can easily come frustration. “I can't do what I used to do", they say, and of course not; that's in the very nature of things. "As thy days so shall thy strength be" so says the Scripture. Believe it and be at peace.
A failure of memory also comes with advancing age. It has been humorously said that three things occur. First, one easily forgets things, and I cannot remember what the other two are!
One dear old Christian man was getting near the end of the journey and he told his minister that he was disappointed in not being able to remember the promises of the Bible. The pastor then quoted several of them and added, "You can be assured that God will not forget them". That is how the hymnwriter must have felt when he wrote the lines, "And when these failing lips grow dim. When Thou shalt in Thy kingdom come, dear Lord, remember me."
