From where do you get the figure of 30 years? Proper sanitation and some verybasic medicine keep folks alivefor 60-80 years. While modern medicine (whether for good or bad, but of course that’s a whole other debate) has pushed the lifespan even longer. Unless killed by disease, the human body tends to fail at about 70 years.
Back to the OP- After leaving his Ark, Noah drinks until he passes out. His sons find him , naked, sleeping it off in field. On the other hand,there are numerous mentions of wine at celebrations. Again the message seems to be, wine is a good thing in moderation.
