I wrote Alan Meckler and asked to be taken off the speaker's list. I was also going to speak in San Fran. at the China / World 3D Printing Industry Alliance http://www.world3dassociation.com/HTML/en1.html in November which I also had to cancel. China's government is opening a big center in San Fran. for China/U.S. 3DP cooperation efforts and this event will be the grand opening of the center.
My dad (82 years old) had a heart attack last week- they tried to get the blockage open with a stent in the cardiac cath lab, and the stent closed down immediately- so they rushed him off to emergency open heart surgery. That was Thursday night. He's still on life support, but doing better today- so hopefully they can get some of the tubes out of him tomorrow. That's the plan anyway.
He'll have a long recovery due to his age, and I'm his only immediate family left. So there was no way I was going to California for a week- or even a few days when he's here in Florida. He's always been there for me and I need to be here for him now.
