but now I have to undergo chemo again.

So what little hair I have grown is going to disappear again.

My numbers went sky high,

much higher than they were when I was first diagnosed.

So the doctors have decided that I have to undergo chemo again.

And that's what I'm doing.

I've gone through a lot of chemotherapy,

and thankfully, that is now over.

I'm on the mend, and that's all I can hope for right now.

This week, I was diagnosed with Stage IV pancreatic cancer.

Now, normally, the prognosis for this is not very encouraging.

But I'm gonna fight this.

I plan to beat the low-survival-rate statistics

for this disease.

Some of you may have heard by now

that during the holiday break,

I had slight medical problem -- subdural hematoma.

Blood clots on the brain caused by a fall

I endured about two months ago.

For some reason, and I don't understand why,

occasionally, it will cause excruciating pain

in my lower back.

Other times, it's fatigue.

Other times, it's nausea.

It varies.

Cancer is mysterious in more ways than one.

There are moments when, for no reason at all,

I feel this surge of sadness, depression.

It doesn't last very long, but it just takes

over my whole being for a short period of time.

-This man has the Guinness World Record's title

for the most game-show episodes hosted by the same presenter,

who is you with 6,829.

Congratulations. You're officially amazing.

-Thank you very, very much.

It's a tribute to the fact that I've lived this long

and, secondly, to the fact that I've had the good fortune

to be associated with a very popular program.

I realize that there is an end in sight for me,

just as there is for everyone else.

One line that I have used with our staff in recent weeks

and months is that when I do pass on,

one thing they will not say at my funeral is,

"oh, he was taken from us too soon."

Hey, guys, I'm 79 years old.

I've had one hell of a good life, and I've enjoyed it.

And the thought of passing on doesn't frighten me.

It doesn't.
