If they go uphill at 2500rpm and lug the engine, it will fail

But if the engine was designed for 300,000km @ 4000rpm, then it should last 400,000km at 3000rpm.

Note: my figure for 300,000km is just a guess. Honda might have designed it for 200,000km or for 400,000km, I do not know the exact number.

It's an engine. It does not enjoy anything. It is the driver who enjoys it.

The engine will withstand a thrashing every now and then.

I have been driving like a hoon these couple of days, I am getting a bit nervous now because my spoon exhaust can get so loud.

Make sure your engine is wamed up fully before thrashing. This is rule #1.
Rule #2 is to make sure your engine oil is always close to the max level when the engine is cold.
Rule #3 is to not lug your engine. So when you floor the accelerator, make sure you have enough RPM to pull.

he means selecting the right gear to maintain or obtain speed. If you try to accelerate from a slow speed in a high gear you are lugging the engine.

Yup, what yfin said. Say there is a hill coming up, and you want to accelerate quickly. Instead of being in 4th gear 2000rpm and flooring it to get over the hill (and lugging the engine), it is better to use 3rd or even 2nd gear at a higher rpm to get the acceleration.
