Don Caskey, of Ohio, says he has convinced more than 600 strangers to get $40,000 worth of matching tattoos with him, and he’s still going. The 56-year-old was diagnosed with renal cell carcinoma in December 2018 after spotting blood in his urine. Since then, he has connected with hundreds of people in an effort to be remembered long after he expires.

“Getting a mark on each other’s bodies, a forever mark that they’ll never forget, and they’ll keep with them throughout life and afterward, they’ll take it with them when they go, so we’re connected together forever by ink,” he explained. Most of his markings are smaller than the palm of his hand and still have not covered his body. He hopes to fill his skin with 1,500 more designs.
