Yes, James O'Keefe was very interesting. I enjoy keeping fit but I'm not fanatical about it, I run only in bare feet never shoes on the soft or hard sand 3 times a week I do 10k thats enough for me, then I'll jump rope (speed rope) for 30/40 minutes 3 times a week when I'm not running.
Three things I would recommend for anybody who enjoys healthy living.
1. Get an Echocardiography done. I got one done at 50yo I have an extra large heart, my resting heart rate is 35/40 beats per minute, like if I sprint for say 100 metres my heart rate goes through the roof but as soon as I stop it drop dramatically THATS GOLD and my arteries are all in good health. I'll get another Echocardiography when I turn 55yo. cost $250
2. Have a blood test every 12 months to see how your insides are doing because if something is out like your HDL or LDL cholesterol or anything else you can fix it. Like I had Malaria very bad from surfing in NIAS way back in 1984 I spent a week in a Singapore Hospital I was f@#@d up. cost FREE
3. I watched Michael Mosley he's a medical journalist on SBS talking about bad body fat around your major organs Like Michael Mosley is a skinny man so he has a MRI scan only to find out his FMI was 26% around his major organs thats very dangerous for your health. I got my MRI Body Composition done I was hoping to be under 15% I had 12% FMI around my major organs thats heathy as, I was stoked. My Bone Mass was 2.6 thats like steel if you're under 1.6 you'll have osteoporosis. cost $88
4. Here's a fourth to keep in mind, keep of the SUGAR I'm guilty as I eat way to much fruit (fructose) like if I was an elephant I'd be walking around drunk all day. If I have to use sugar in my cooking I've now defected to DEXTROSE. I'm not a fast food eater, but if I do it's very rare.
To books I would recommend to read you'll find them in the library.
