Yah, I don't think it's the loss of information, but a related concept: it's a decline in order.

We have a whole lot of redundancy and mechanisms to restore/repair redundancy. But even so, there's a march of entropy upwards; oxidation, genetic damage, cell death, tissue damage, neuron loss, etc.

We don't have repair mechanisms for everything the body knows how to build, and the repair mechanisms that we do have become less effective to use (and often less safe) as the body ages.

> it's a decline in order.

That is another way of saying loss of information and increase of entropy.

While the thermodynamic and the information theoretic concepts of entropy are related, it's not really applicable here. All the "real" information in the system is highly redundant (except perhaps neurological)-- we have billions of copies of the "information". The system's ability to restore itself to the order specified in the plan is lacking.
