Be nice to old people

You shouldn't make old people angry. The older they get, the less "life in prison" is a deterrent.

Good one, Glenn!

You are right, we must try to behave better with old ppl.
Not all seniors are at risk of developing an anger problem, but there are some circumstances that may lead to anger issues in older adults. For example, physical health problems can affect your overall mental and emotional state. If you feel frustrated, trapped, or out of control because of your health issues, anger at your situation might start to creep into your life. Then, when you already feel so stressed and anxious, it doesn’t take much to set you off. A small obstacle or inconvenience can feel absolutely infuriating when you’re dealing with so many other frustrations at the same time.

Sleeping problems can affect your mood as well. Some older adults struggle to get adequate deep sleep every night. Lack of quality rest can make you feel irritable, impatient, or on-edge throughout the day. You may lash out at others for small mistakes because your brain hasn’t gotten the rest it requires to withstand stress.

The social and emotional challenges that come with age may affect your levels of anger, too. Feeling lonely or isolated can be very frustrating, and you might experience anger if you feel like no one is listening to you. Anger is a common response to grief and loss as well. Although your retirement years can be an incredibly meaningful time, there are also some common hardships that happen at this stage in your life.

It was a joke.

Gotta admit though, that long, serious reply made your joke all the funnier!

True - at my age, it's always nice to know someone is paying attention.
