Imagine your body is like the house you live in．Every day, your family creates rubbish．The rubbish builds up until it is put out for the weekly garbage collection．
Now, say you put three bags of garbage out．but because one of the collectors was away sick, only two bags are collected．You take the leftover bag inside to be put out again next week．The following week you put on another three bags．plus the leftover bag from last week．But again, only two bags are collected．Imagine this cycle is repeated over the following weeks．
This is a simple description of what happens to your body when your kidneys (肾脏) don't work efficiently．Your body is nol thoroughly emptied of waste products．Other areas of the bodv such as blood pressure and red blood cell production are affected and the insidious process that may lead to kidney failure begins．
It's not uncommon for people to lose up to 90% of their kidney function before deveoping any symptoms．There may be no warning signs. This makes early detection (诊查)difficult．
Kidney's main job is to remote toxins(毒素) and unwanted water from our blood．Every day our kidneys clean an average of 200 litres of blood．Kidney failure may be a gradual and silent process, going unnoticed because there is no apparent pain．
Research shows that more than 35% of the patients requiring dialysis (透析)do not see a kidney specialist before they have to do so．Some risk factors for kidney disease such as age and genetic make up are out of our control; however, some changes in lifestyle may help prevent kidney damage．Two major risk factors for kidney disease, diabetes (糖尿病)and high blood pressure, have been on the rise over the last few decades．Both conditions are chiefly affected by being overweight and not getting enough exercises, which are the potential risk factors for the kidney disease．

When I was an education official in Palo Alto, California．Polly Tyner, the president of our school board, wrote a letter that was printed in the Palo Alto Times．Polly's son, Jim．had great difficulty in school．He was classified as educationally disabled and required a great deal of patience on the part of his parents and teachers．But Jim was a happy kid with a great smile that lit up the room．His parents acknowledged his academic difficulties, but always tried to help him see his strengths so that he could walk with pride．Shortly after Jim finished high school, he was killed in a motorcycle accident．After his death, his mother submitted(提交)this letter to the newspaper．
Today we buried our 20-year-old son. He was killed instantly in a motorcycle accident on Friday night. How I wish I had known when I talked to him last that it would be the last time. If I had only known I would have said, “Jim, I love you and I’m very proud of you.”
I would have taken the time to count the many blessings he brought to the lives of the many who loved him. I would have taken the time to appreciate his beautiful smile, the sound of his laughter, his genuine love of people.
When you put all the good qualities on the scale and try to balance all the irritating phenomena such as the radio which was always too loud, the haircut that wasn’t to our liking, the dirty socks under the bed, etc., your angry feelings won’t amount to much.
I won’t get another chance to tell my son all that I would have wanted him to hear, but, other parents, you do have a chance. Tell your young people what you would want them to hear if you knew it would be your last conversation. The last time I talked to Jim was the day he died. He called me to say, “Hi, Mom! I just called to say I love you. Got to go to work. Bye.” He gave me something to treasure forever.
If there is any purpose at all for Jim’s death, maybe it is to make others appreciate more of life and to have people, especially family members, take the time to let each other know just how much we care.
