Grumpy old people

Yes, particularly the elderly who are discontent and frustrated with modern society and how starkly different things are compared to their era.

Yeah I do find myself quite grumpy in my old age. I'd largely say it's a mix of things. An accumulation of life experiences can wear you down making you bitter. Today is much different than yesterday with tomorrow looking more so. Change is scary and unfamiliar. Our bodies eventually hit their peak then it's just a gradual decline in health until we die. The close we get towards the end of our journey in life the less people we had since the beginning. To sum it up I'd say time hardens us.
