Truly sad news for so many of us.
As with voices on the radio in the past, prior the internet, where I would conjure up a picture of the speaker from his / her voice, so I imagined Ubon Joe, but from his proficient and prompt, to the point, and knowledgeable replies . His sheer volume of responses conjured up someone in his 40s to me. A person with experience but still full of energy.
In fact he was much older,
altruistic to the end.
