A quick hello is all it takes for others to form a snap judgment of you, according to a 2014 study whose authors found that it takes no more than that one-word greeting for a listener to decide how likable and trustworthy you are. And, accurate or not, those instant impressions often stick.
As you enter your 60s and 70s, your voice starts to change. Your vocal folds weaken, cartilage in the larynx begins to ossify, and your respiratory system (which helps power your voice) begins to work less efficiently. The result? Men's voices go up, and women's go down. You may start to sound breathy or wobbly or hoarse. It's a common part of growing older, but it can affect how others think of you and how you think of yourself.
