Contrasting Ages

The old man rises daily through will
The younger man has too many excuses still
The old man has aches and pains
The younger man does nothing but complains
The old man's days are limited
The younger man has barely contributed
The old man's life is full
The younger man's life is push and pull
The old man's nature is respecting
The younger man's nature is expecting
The old man has already created
The younger man's ego is inflated
The old man's mind seems clear
The younger man's mind is filled with fear
The old man has many true friends
The younger man relates based on trends
The old man remains daily busy
The younger man's life is lived in dizzy
The older man fought on other shores
The younger man doesn't open any doors
