Life is transient

A colleague wrote this to me. It was so well written that it would be a waste not to share it.

"I visited a friend whose wife is suffering from lung and brain cancer in Tan Tock Seng Hospital a few nights ago. It was a good break from marking exam scripts. My friend and I have DownSyndrome children. When I saw him at the hospital that night, he was looking at his wife who was drugged with morphine, his hand on the bed railing, a total picture of calmness and acceptance.
My wife went and stroked his wife's hair, and speaking words of encouragement to her still body. My friend and I spoke. After an hour, we left.
I can still remember these few words from him: "We were retired for a few years and had plans to stay in Australia for a few months with our son who is graduating from the Uni there. My wife is a very healthy person, waking up at 5am, go for walks. Then this thing happen. Life is very transient."
As we journey on this earth, sometimes we think we are in control of our lives. Most times, we find life is transient and we need friends, our wives and for most of us, we need God. "

Another colleague added the following:
"People feel sad when their loved one is leaving them.
When we eat meat, have we thought of the suffering, pain and fear of the animals caused by our greed?"
