Thinking: When someone is making a decision or thinking about something, you will notice how they slowly raise their hands and start stroking their chin, they might also play with their beard if they have one or sometimes fiddle with their lips stretching them out or squashing them together. This can often be seen at the supermarkets when someone can't decide whether they should buy the low fat yogurt or risk buying it and venture into the unknown to purchase the new flavored full fat yogurt that just came out.
