Since US-based researcher, John B. Goodenough is not too old to work in his 90s, he is not too old to work to win the Nobel at 97.
This appears to be the judgement of the Nobel Prize for Chemistry judges who have awarded him the prize..
Goodenough is a few months older than 2018 Physics Prize laureate Arthur Ashkin, said Goran K Hansson, permanent secretary of the Academy.

Goodenough turned 97 in July.
He shared the 2019 chemistry prize with Stanley Whittingham and Akira Yoshino.
Hansson said the Academy had not reached Goodenough prior to the announcement, and did not know if he would come for the December 10 award ceremony in Stockholm.
s Nobel Chemistry Prize with two others
97-year-old John Goodenough has emerged the oldest Nobel Prize winner across all fields.
Goodenough is one of three researchers who won the Nobel Chemistry Prize on Wednesday for the development of lithium-ion batteries, paving the way for smartphones and a fossil fuel-free society.
Goodenough, Britain’s Stanley Whittingham, and Japan’s Akira Yoshino will share the nine million Swedish kronor (about $914,000 or 833,000 euros) prize equally, the Royal Swedish Academy of Sciences said.
“This lightweight, rechargeable and powerful battery is now used in everything from mobile phones to laptops and electric vehicles… (and) can also store significant amounts of energy from solar and wind power, making possible a fossil fuel-free society,” the jury said.
“Lithium batteries have revolutionised our lives since they first entered the market in 1991,” and were “of the greatest benefit to humankind”.
This year’s Nobel season kicked off on Monday with the Medicine Prize awarded to Americans William Kaelin and Gregg Semenza, and Britain’s Peter Ratcliffe.
