How olds the oldest person to beat you at arm wrestling?

I know an old man over 90 ,and he is strong as an ox
I met some of his friends ,and they are strong also
there is a community that has been reported on by many news sources and turns out that is where he comes from ,a place where most citizens are over 100 ,they still work and drive ,,put in gardens and go for very long walks .
Here is the City
3. Loma Linda, California

East of Los Angeles, Loma Linda is a community that includes about 9,000 Seventh-Day Adventists — a religious group that is significantly longer-lived than the average American. Adventist culture is focused on healthful habits such as vegetarianism, and warns against alcohol and smoking.

Secrets of Longevity: Besides the healthful habits integral to their belief system, Adventists drink plenty of water, eat lots of nuts, exercise regularly and tend to maintain a healthy weight. They nurture emotional and spiritual health, value their family relationships, and prize volunteering.

I know another man well over his 70's ,he rides a bike over 100 miles a day
So though I do not live the lifestyle they do ,I have to admit they are living proof .
Wish I had known about them when my back was not eat up by a bone disease .
But I am stronger then most men I know ,I use a lot of upper body to protect my back and my knees
But I do think that old man could whip me LOL
He about breaks your hand just to shake hands with him
