I&#x27;m a little troubled by the argument that an increase in the probability of death signifies or is equivalent to an increase in the rate of aging. I feel like that conclusion doesn&#x27;t follow and is misleading, but I&#x27;m not sure. Am I off base?<p>If we suppose humans live to around 85 years on average, and rarely if ever die before 65, then there&#x27;s a big bell curve normal distribution on 85, and what looks like a non-linear exponentially increasing probability of death up to about 80. But that doesn&#x27;t mean everyone started aging faster at 65, it just means people started dying around 65.<p>Imagine that you go bowling and throw 20 mph balls on average. The distribution would look similar. Bell curve on a pin dropping at around (say) 5 seconds, but the curve starts at around 4 seconds and ends at 6ish. Does this mean the ball suddenly accelerated at the end? No, in fact the opposite happened, it was slowing down. But the rate of probability that a pin goes down is exponentially increasing from 0-5 seconds.<p>Not a perfect analogy to aging by any stretch, but am I right that an increase in the probability of death is unrelated to aging - the speed at which we approach death?
