How do you appreciate the role of esters in everyday life?

Esters are useful to us in many ways in every day life.
Esters are sweet smelling substances. These are used in making perfumes and flavouring agents.
Esters react with acids or bases to give alcohol and the carboxylic acids.
Esters are used in saponification to prepare soaps. Hence I appreciate the role of esters in every day life.
