I had a similar idea last year. Your heartbeat would be registered on-chain. Proof of existence (life) :)
Thinking of it, I made a twetch about it back then:
twetch#3242 7.3y
At an average of 80 heart beats per minute, it costs $18.22 a day to register every single heartbeat on chain.If done at interval of 1 minute, it costs $6651 in tx costs from the birth of a baby till death at 80 years, average of $83 a year, $6.92 a month.
