Reducing engine speed to keep an engine working

I drive a petrol Ford Focus mk1 which is 8 years old. When overtaking cars on I get to about 6,000 and then change gear. Would revving the engine to these revs damage the engine especially at the age of my car? If it does damage the engine what parts of the car are likely to be affected?
Probably better to keep your revs down to 5,000 now the engine is getting old.
