From a surgical point of view, this is a wonderful idea.
We may wear special eye glasses and we can see exactly where the malignant cells or tissus are.

Listening and seeing her....
The Vietnamese people are "up and rising" groups of people in the modern world.
They are not what they seem, just small, unattractive, and dark colored.
Not to be just brushed off. You all know what I mean as we are not much defferent from them.
Looking back the long way we have walked on in this society,
for the same way, they might even exceed what Koreans have done.
It shows in the 1.5 or 2nd generation Vietnamese that I have seen.

A lot of them are very smart and tough.
I am sure Q. Nquyen is one of those.

If we can selectively mark different tissues, using coloring agent or light emitting agent 
(e.g. cancer, nerve, muscle, etc,..), we may not be far from selectively target cancer cell
and destroy by chemotherpeutic agent via local artery ro deliver only to cancer cells?,
or shoot laser beams etc. 100 years later, medicne will be very diffferent.

1. No wonder they predicted human being would live up
to 200 years old by 2050 at the turn of the millenium.
( Japan now, 82.6/ S. Korea, 78.6/ USA, 79.4)

2. As WM noticed Vietamese are coming very strong.
We have 3 special high schools in New York(public)
and I heard from my children Vietnamese students
were doing very well in their class. When my Michelle
graduated, the Valedictorian was Vietnamese to my
surprise.

3. If human longevity increases at this pace, every
government will have huge burden to help oldies
in their later life. It seems to me human life span
increases by one year every 2 to 3 years.

60s and 70s are No Longer Oldies any more.
They are Young Chickens in my practice.
