You left out murder and war.

I doubt it will be awkward. It will be viewed that aging is a disease, that we have the cure now, so there's one less way to die. Getting rid of polio didn't make the other ways of dieing more awkward.

Most lives already end with a disease. You don't die from old age.

Investing in things other than not-freaking-dying - now that's awkward.

Would have profound impact on how we value our own lives (and others). If you are 60 you might get a motorcycle because what the hell. Worse case you crash and lose 20-30 years of which only 10-15 are good. With aging out out the window you could have centuries to lose.

There is also a slow dissolution into a different state of being.

I imagine humans living long enough to begin augmenting their bodies and brains into a thing that no longer resembles the original being. Or even a form of life as we understand it today.

Or starvation.

Or not taking the cure.
