This underscores a good point....we never know when, or what may befall any of us, and some of us are only known by the forum(s) we attend. If I 'go under' my dear wife wont be posting about it, and who would know.
I guess its kind of the nature of 'the beast' (internet) with the ambiguity. Worst part is, that we will lose some friends over time and wont know.
