The weight of a field gun is a compromise between being light enough to carry all day and heavy enough to shoot well when the time comes.

Presumably, we become better shots with age and experience. We also (in some cases at least) are out there for a slightly different reason than youngsters. We have lost the desire and need to kill everything that might go up just to prove that we can. Quality of experience becomes more important that quantity. This is called 'maturity'.

A lighter gun adds measurably to the enjoyment of the day.

There's a fine line between turning into a big pussy and just getting smarter about the hunting concept as a whole.
