The real consequences of concussions don’t usually take place until years down the road with diminished mental capacities. They don’t usually kill at such young ages.

In other words, you don't have a clue why he died.

So would it hurt you to show some kindness, and wait until the facts come out?

Thanks.

It’s not unkind to engage in a little speculation.

The facts will speak for themselves.
