Tomiji Suzuki, 89, started coding in retirement and is now making apps for Japan's fast-growing elderly demographic, using ChatGPT to fine-tune his skills.
So far, Suzuki has developed 11 free iPhone apps to help Japan's aging population, including his latest: a slideshow of items to remember when leaving the house, from a wallet and hearing aids to patient registration cards.
He was inspired to create the app, which features his granddaughter's voice, after he realized he had forgotten his dentures as he was about to board a bullet train.
