+
+1.	**Realistic Forecasts**: In many real-world scenarios, it's unlikely for a trend to continue indefinitely at the same rate. For example, if sales of a product are increasing, they might not keep increasing forever at the same rate. After a certain point, the growth might slow down. Damping takes this into account.
+
+2.	**Avoid Over-optimistic or Pessimistic Predictions**: Without damping, the model could make overly optimistic (for upward trends) or overly pessimistic (for downward trends) predictions for long-term forecasts.
+
+3.	**Stability**: Damped models often provide more stable long-term forecasts, especially when the data has some inherent variability or noise.""")
