ELI5: How do doctors calculate the amount of time dying people have until they die?
gpt
The doctors don't calculate much, they look at statistics on the average survival time/rate of people at similar stages of the disease in the past. With experience doctors get quite good at estimating the situation and guessing somewhat precisely but that does not mean the estimate is exactly the time a person has left. If a doctor says you have 3 months left you could still die next week or live another year.
