Hi there and welcome to my cyberhome, I am a geek living in Scheveningen, The Hague, The Netherlands. You can find some code I've written on GitHub and on the research page of The National library of the Netherlands. Fe2 stands for Iron, the chemical element which binds us all. Our blood contains Fe2+ to bind the free oxygen from the air, and transport it to our brains. Also the atomic number of the element Fe (ferrum) happens to be my dob: 26.
