Last night, I was having a conversation with two friends about my recent travels when one mentioned how impressive it was that I didn’t seem to suffer from jet lag going either direction. I told them that it seems my sleep/wake cycles track the light very closely and so, wherever I am, I find my sleep schedule quickly adapts to match the relative light exposure. One friend, quite amused, quipped that my light-adaptive sleep behaviors would’ve served me quite well in the time of the caveman. To this I contested that it probably wouldn’t have mattered much in the time of the caveman, because access to long distance transit mechanisms was non-existent and thus they likely wouldn’t have had the means to experience many time zones anyways.

Having said that, an intriguing question popped into mind that I couldn’t seem to shake. I posed it to my friends, asking “What is the maximum number of time zones a determined caveman could realistically traverse in his lifetime, assuming his only methods of transit are walking or swimming?”

Brainstorming a Path

I immediately recalled the alleged longest walkable distance which journeys from the furthest tip of Russia to the southernmost tip of South Africa. This is a good starting point for distance optimization, but unfortunately this is not an ideal route as a large portion is predominantly vertical and not too many time zones are represented in the African leg of the traversal.

Alright friends, I asked and you delivered.

I will now do my best to return the favor - let’s dive into web3 identity.
