Reaching the age of 100 is a remarkable milestone. But reaching 100 while still mentally sharp, physically active, and full of life is even more extraordinary. Dr. Hiroshi Tanaka, a Japanese physician who recently celebrated his 100th birthday, is living proof that age truly is just a number — when you live right.

With more than 70 years of experience in medicine and decades of observing human health firsthand, Dr. Tanaka has distilled his knowledge into 7 simple yet powerful habits that he believes have helped him live not just long, but well.

Here are the 7 daily habits this 100-year-old doctor recommends to everyone who wants to live a longer, healthier life:

1. Wake Up with Gratitude

Every morning, Dr. Tanaka spends five minutes thinking about what he is grateful for. Whether it’s his family, fresh air, or simply waking up pain-free, he starts his day with a positive mindset. “A thankful heart is a healthy heart,” he says. Studies show gratitude can lower stress and improve sleep and immunity.

2. Move Every Hour

Even at 100, Dr. Tanaka doesn’t sit still for long. He makes sure to stand up, stretch, or walk around every hour — even when reading or watching television. “The body is made to move,” he explains. Prolonged sitting has been linked to heart disease, diabetes, and even early death.

3. Eat Until You're 80% Full

This habit comes from the Okinawan concept of Hara Hachi Bu — eating until you're just 80% full. Dr. Tanaka says this helps avoid overeating and supports digestion. His meals are small, balanced, and full of vegetables, fish, fermented foods, and green tea.

4. Practice Deep Breathing

Every afternoon, he takes 10 minutes to practice deep breathing — slowly inhaling and exhaling while focusing on his breath. This calms the nervous system, reduces blood pressure, and improves oxygen flow. “Breathing right is the foundation of health,” he says.

5. Stay Curious and Keep Learning

Dr. Tanaka still reads medical journals and learns new things every day. “The brain needs exercise too,” he insists. Keeping the mind active through reading, puzzles, or even learning a new language helps prevent cognitive decline.

6. Sleep Before 10 PM

“Your body heals when you sleep,” he reminds us. Dr. Tanaka goes to bed early and wakes up early, following the body’s natural rhythm. Quality sleep is crucial for immune function, memory, and cell repair. He avoids screens and heavy meals at least an hour before bedtime.

7. Connect with Others

Finally, Dr. Tanaka highlights the importance of social connection. He speaks with his children, friends, or neighbors every day — even if just for a few minutes. “Loneliness is more dangerous than smoking,” he warns. Meaningful relationships improve mental health and longevity.

Final Thoughts

Dr. Tanaka’s advice isn’t based on fads or trendy diets. It’s grounded in a lifetime of observation, science, and lived experience. None of his habits require expensive products, gym memberships, or complex routines. They’re simple, consistent, and available to everyone — regardless of age or income.

He concludes with this message:
“You don’t need to wait until something goes wrong to start living healthy. Begin now. Take care of your body, your mind, and your spirit — and they will take care of you in return.”
