One secret to living beyond 100 years: Know what it is

One of the most touching moments Dr Scharffenberg shared was about a conversation with his colleague—a graphic designer who was struggling with obesity.

He didn’t judge. He spoke from the heart, with facts and hope. He explained the serious risk of being overweight, especially when it comes to diseases and early death. But more importantly, he shared this powerful message: "Even if someone is obese, if they exercise daily, they can still live longer than someone who is thin and inactive."

That honesty, mixed with encouragement, reflected his genuine wish to help others live better—not just longer.
