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 not thoroughly emptied of waste products.Other areas of the body 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 developing any symptoms.There may be no warning signs. This makes early detection (诊查)difficult.
Kidney's main job is to remove 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 obvious 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 (潜在的) risk factors for the kidney disease.

Writer and power chair adventurer Mary Laver has not walked for twenty years. Yet the cheerful and positive 60 year old is not only refusing to let her disability get her down ---- she is also planning to cross the length of Britain in a power wheelchair.
Getting ready for the trip is not easy. She has already run into many problems - not least officials and organizations who view her as a health and safety risk. One police officer wrote to Mary requesting:
1. The proposed route through our area with road numbers.
2. The dates and times each day that this will be taking place.
3. The location details of the proposed overnight stops.
4. The names and mobile phone contact details of the Support Crew.
Another police officer asked her to travel off road! As Mary told me, this was unacceptable - as a power wheelchair user with limited movement she needs to be "gettable".
There are other problems in her way though - she is, after all, in her 60’s and has severe rheumatoid arthritis(风湿性关节炎). However, unlike many other people with arthritis, she is no longer in pain.
"When you are in a power chair and it is going at eight miles an hour, believe me it feels fast … to me it is the Formula One(一级方程式赛车) chair of electric wheelchairs."
At the end of the interview, I asked Mary if she had a message for any other power chair users who wanted to do a challenge, and her reply was simple:"Just do it!"

2. Why did a police officer write to Mary requesting the four points?
