  I think it depends on my mood. My chemistry is quite dangerous, it is explosive at -4 degrees, it causes cancer, it catches fire in the presence of air so when i am doing reactions i have to be careful or i could hurt myself and the people working near me.
  
  I think the project i chose makes me seem like a daredevil but i would be an idiot if i didn’t take it seriously.
