I am 80.5 years old, and I can easily clear 4 foot high hurdles. I eat fried foods a lot such as fried chicken and fried shrimp. I also like pizza with sausage & cheese.
I seldom eat any of the healthy foods listed in OP (original post). Because I have found the best method to stay young...aerobic treadmill exercise EVERY DAY covering 1.10 miles at 24 miles/hour speed and set 2 degrees up slope. This has made it possible to quit taking my blood pressure medicines, all aches and pains in hip joints and knees are gone, and I can even remember what I had for breakfast LOL.
Age 100 looks easy target if I can drag my butt to the gym for treadmill every day. Goal is to reach 100 without aches and pains and zero medications.
Congratulations...

Don’t you think that’s a little “tall” for somebody your age?
Yeah, but it's just getting back up off of there that is the big problem.

“...aerobic treadmill exercise EVERY DAY covering 1.10 miles at 24 miles/hour speed...”
Hmmm - Usain Bolt’s average speed in his 100 meter world record sprint was 23.35 miles/hour.
You can do a mile at 24 miles per hour?
Man.
I choose you to be on my track team.
That is wonderful. Congratulations.

The way I read it is that you can clear 4 one foot high hurdles. :)
