Proverbs 20:29

The glory of young men is their strength, gray hair the splendor of the old..

This applies to all cultures. You won’t see people in their 60s participating in the Olympics. Likewise, only a fool like King Rehoboam (see I Kings 12:8) would give more weight to the “wisdom” of young men over that of the older, more experienced men. In each stage of life, men and women have something special to offer. Young men can do necessary physical work. Old men can offer advise based on their many years of experience.
