All the while forgetting that benefit is heavily skewed.

Those that would really benefit from its protection are often the same group that would be knocked sideways by its side effects (the very old, infirm, already sick or otherwise vulnerable).

The majority get nothing much in terms of side-effects, but also nothing much in terms of protection over what our bodies could already do for us.

There’s only a small group that are vulnerable enough to benefit significantly, while also being strong enough to tolerate it.
