For me 76°F is cold and at 69°F I begin to shiver. I'm used to temperatures ≥ 90°F almost every day. In fact my room has been lately getting at 94°F at night while 86°F at the outside of the house (at night). Therefore, I'm very sensitive when it comes to drops in temperature. Anyway, what about you? What is cold for you and when do you begin to shiver?
