           Do you know Why Old books go to Therapy ? Because they have a lot of unresolved "twists" in their back 🔙 . 😅

Come Lets find why old books have a enigmatic fragrance.

Trees 🌴 = Paper📄.....Paper is made of wood pulp which contains a compound " Lignin " , a complex organic polymer. Lignin reacts with oxygen to become tinted with yellow color. When Sunlight and Heat 🔥 react with this Yellow paper to form "VOC" or Volatile Organic Compounds ( Basically Good Smelling gases ).

So whether it is a newspaper or a 12 th grade Maths Book 📙 Smell is more important than what is inside !!
