Final answer:
The man's condition in the last stage of life in the poem 'All the World's a Stage' is old age, characterized by weakness, sorrow, and isolation.
Step-by-step explanation:
"All the world's a stage" is a monologue from William Shakespeare's play "As You Like It," and it describes the seven stages of a man's life. In the last stage, often referred to as the "sans teeth, sans eyes, sans taste, sans everything" stage, the man is characterized by the loss of various faculties and bodily functions. This stage represents old age and the decline of the body and senses. The phrase "sans" means without, emphasizing the man's deprivation of essential aspects of life. It portrays a stage where the individual has lost teeth, sight, taste, and other vital elements, symbolizing the inevitable effects of aging and the ultimate frailty of human existence. Shakespeare uses this poignant depiction to reflect on the universal and cyclical nature of life.
