I achieved the level of "Neanderthal", but plan to stop at "Cro Magnon" level.
I do not smoke at all...I vape. So I am already a happy, successful Neanderthal!
I am planning to evolve to the stage of getting a device that allows me to experiment more with different ejuice...something with a clearomizer, maybe a 777 Bullet. Buy my chosen ejuice, fill the clearomizer...vape away. Even a cave-man (person) can do that! I like and prefer a cigarette-style vaping device.
I probably won't evolve past Cro Magnon: vv batteries, tanks, meters, mods...all very cool, don't get me wrong, but all I want to do is run around, happily vaping, with minimal muss and fuss. Once I have the flexibility to switch brands and flavors of ejuice, I will most likely find my level as a happy Cro Magnon.
...unless all this stuff that I am reading about sneaks up on me and captures me...
