yuors life depend on good brakes can you afford

Depends on mileage, the reason it is recommended is that brake fluid is vented to the air because it expands when heated during brake operation, because is vented it will absorb moisture from the air and then the boiling point will lower and can cause brake fade especially when coming down a pass and may be riding the brakes and not letting them cool down. Loss of pedal pressure in this instance can be frightening. Moisture inside the brake fluid can accelerate the brakedown of internals in the brake system. Fluid may still look good but that is why it is recommended so brake system has a chance to remain in top shape. I personally feel the most important system on any vehicle is the brakes. But of course it is your call. By the way, if you use synthetic brake fluid it does not absorb moisture.

Agree with Raderron's great answer. Flushing the brake hydraulics is very important part of maintaining brake system health. I like to suction bleed the brakes rather than replacing the brake fluid by having someone "pump" the brake pedal. But and this is important do not use synthetic DOT 5 brake fluid in your car particularly if it has ABS brakes. Use a good name brake DOT 3 or 4 fluid.
