Knowledge: The introduction of automated mixing and kneading machines has made baking require less physical effort.

Conversation:
My sister is a baker. She bakes mostly cakes and pies and other pastries.
A baker is someone who bakes.
Yes, like my sister. Haha! What else do you know about baking?
It has to do with breads and other products made using an oven.
Definitely. My sister can make some of the best pastries in the area but she will be exhausted by the end of the day.

Response: That sad! I would suggest buying an automated mixing and kneading machine, which will make baking require less physical effort.
