Completely miss the point there. The basic principle behind entropy is that any ordered system will eventually become disordered over time and reaches equilibrium. Some systems go easily disordered within within a human lifetime, or even in seconds. For example, add milk to you coffee and watch it become diffused.
In the context of a human body, the coded information in our DNA, the structured cell walls in our body, are states of matter that is low in entropy. They will eventually get damaged due to interactions with other matter around us. The damage in this case will manifest itself as "aging".
The original comment just says "because of entropy". It's not an explanation, it's an appeal to a black-box technical term. So I pointed out an obvious way in which that term did not apply, since we're rather further than 100 years from the heat death of the universe.
Yes, human bodies by default incur damage and stop functioning within ~100 years. But what prevents that damage from being repaired, other than our ignorance? Are you/they actually claiming it literally violates the laws of physics to repair a human body? Because if not, I reject the appeal to entropy. Entropy is a very specific thing; it is not a generic stand-in for "stuff must break down".
How is GP missing the point? They're arguing about the timescale of entropy, not the basic principle. You're right that ordered systems eventually become disordered, but "eventually" can mean 10^100 years, and you haven't provided any evidence to the contrary.
your body is getting damaged constantly and it is repairing the damage constantly. You are able to do this - in terms of entropy - because you are not a closed system, you are eating food and breathing air. Entropy is not an insurmountable problem for an animal unless it stops eating and breathing, just as entropy is not an insurmountable problem for an electric refrigerator unless it stops receiving power
