About Seppo
A life
lived in steam

I was born in Finland — the country with 3.3 million saunas for six million people. I have used a sauna since before I can remember, and I intend to keep using one until I cannot.

"I experienced clinical death at 55 and recovered without hospitalisation. The doctors credited my cardiovascular fitness. I credit the sauna."

At 77, I am learning Spanish — my second new language in consecutive years — performing better than 95% of Duolingo users of any age. I work eight to ten hours a day on things that genuinely motivate me. My target is 100 countries before I am 100 years old.
