remember a story about a pink crocodile? yeah, me neither

I just did the inexplicable thing. I don't know if I'm going to regret this later, but I just can't help myself.

Wallahi I don't know how to let go.

You, my dear,  like the HeLa cells that stuck on the bottom of the tissue culture well. No matter how hard I use cell scraper to remove you, and trysinize you, at the end of the day, when the medium is all evaporated, I can still see traces of you.
And you, my dear, like HeLa cells, are immortal. The host may had died for 100 years, but the little pieces are still around, and growing exponentially.

So tell me. How?
