What are the age-revealing practices of the people around you that make you feel they are old?

They will click on the CCTV news channel when they grab the remote control with you, or watch some anti-Japanese war or family ethical dramas, and are very resistant to you watching Japanese, Korean and American dramas. These people are generally more old-fashioned, so they are not very interested in new things, and when you see them doing this, it's like they are silently telling you that they are getting old.
