Yes, it is more difficult. Just observe children, it's delusional to deny it. The biological decay is obvious - for now - but the mental factor is way underrated. Mature people often don't have the time or the mental space to dive into something and "forget the world" like youngsters have. Almost without exception mature people prioritize their family or at least they are accountable for it. They may find time after retirement but then the biological decay will be more advanced. During college (Architecture, a field dependent on creativity) I remember hard-working colleagues in their 40s and 50s, people with jobs, sometimes family and they couldn't pass the same bar as the youngsters. While youngsters could spend days debating some theory and shaking it till the foundations, older people barely had the time and mental space to execute. I heard literally teachers saying that they had to lower the bar for them or they would be there indefinitely without major improvements.
