 Barracuda Terrorist
Good morning! 
Greetings!

 

I almost died from a barracuda attack 5 miles off the Florida Keys last week.

 

As one could understand, I've had trouble discussing what occurred. I've not shared this extremely private matter with anyone outside of immediate family and a Walk employee until now.

 

I'm 'opening up' as I feel this incident can serve as a lesson to us all. The lesson, my good friend, is fitness. A superior level of fitness that saved my life and almost certainly the lives of dozens of my fellow shipmates. Yes Virginia, we now have one more reason to Walk with a Doc.

 

Tuesday, March 15th started like any other beautiful Key Largo morning. My family, in-laws, and I were aboard the U.S.S. Dolphin. The Dolphin is a fine seaworthy vessel that sailed us due west out of John Pennekamp Coral Reef State Park. 

Onboard the ship, we partook in a bountiful packed lunch of Cheese Whiz and luscious pomegranates prior to arriving at our final destination; an awe-inspiring coral reef displaying dozens of various purple hues. It was teeming with tropical fish of unique sizes and shapes, sea anemones, lobster, and a moray eel or two.

 

I was ready and fitted with perfect attire. My wetsuit, goggles, snorkel, and flippers were snug. Against our guide's conservative advice, I held my nose and did a sitting backflip off the side of the boat. There is no question that I was impressing all the ladies, right up until I whacked my right leg against the ladder and my head against the hull of the boat.

 

As I was coming to, I found myself mesmerized by the beauty of the abundant colors that lie underneath the massive Pacific.

It was then, and rather immediate, that they came to my attention - several man-eating barracuda, about 35 yards away. Let me tell you, they look even more dangerous in real life.

As I studied them, their method of attack quickly became evident. They were pretending to ignore me. Brilliant and exactly what one might expect from the ocean's most feared predator - they were attempting to lull me into a false sense of security! 

 

Well Mr. Barracuda, not me, not us, not today.

 

I was determined to alter what these mighty barracuda had in store for our crew. I had no choice, lives depended on it.

 

What followed was akin to a single person lifting a Chevy Suburban off a 7 year-old child. It was a series of involuntary events that science could not explain. 

  

Initially, I was overtaken by a sea of inner calm that impressed even myself. Then, operating on pure instinct, I rapidly began motioning fellow snorkelers back onto the vessel.

To a person, they repeatedly ignored my requests.

 

This left me no choice other than to take on the mighty beasts - Mano y Mano.

 

I've had my nay-sayers along the way, but my 11 year commitment to establishing the discipline of Underwater Karate (ka-rah-TAY) was suddenly very much in need. Apparently it has had a role all along (sorry haters).

 

Next, I quickly cycled through what I felt were the 7 most appropriate Underwater Karate moves that the moment called for. After this exhaustive 45 second frenzy of sight and sound, I opened my eyes (finishing in the Zen-Kutsu dachi position).

 

Just as I had suspected - it worked.

 

There was not a barracuda in sight and everyone was safe. It still sounds so sweet - Everyone Was Safe.

 

It wasn't much later that we were resting on the sun-drenched deck of the catamaran counting off. It was all I could do to fight back tears of pride.

 

Walk with a Doc had provided me a superior level of fitness that had saved us all.

 

In the decades that follow, as fellow passengers share these stories with their children and grandchildren, I hope they remember one thing.

 

Fitness doesn't only make us look good in Speedos.

 

One day, one day... it might just save your life.

 

Thank you fitness. Thank you so much.  

 

(right now I am standing in front of my computer bowing...and crying like a baby).

 
 
 
Fish Oil 

Seems like the appropriate newsletter to have this discussion.  Let me apologize in advance, as I fear I will offend many. What follows is my opinion of the data and does not represent anyone else's views but my own. Okay, here we go. 

 

Does this stuff really work? If so, what's it do? Good question. Yes it works. It improves HDL (good cholesterol), lowers triglycerides, slightly increases bleeding time, reduces inflammation (things ending in 'itis'), improves brain function & memory, stabilizes heart rhythms, and possible coronary arteries. Some studies have also shown it to alleviate symptoms associated with depression and other mood disorders, and possible reduce your risk of cancer.

 

What's matters to me is that in the end it is definitively proven to do at least some, if not all of these, and most importantly there is no strong reason not to take it. Fish burp is the biggest complaint. Heehee - fish burp.

 

Wait a minute. Increases bleeding time?! Can I still take aspirin and other anti-platelets or anticoagulants? You need to discuss with your own physician, but I tell most all my patients that yes you can. 

 

I hate fish and fish oil - can I take Flax Seed Oil? Absolutely, it just doesn't work near as well as fish oil.

 

What do you mean? Flax seed oil is broken down into ALA (Alpha-linolenic-Acid). ALA doesn't do much, but it gets broken down into EPA and DHA which does. The conversion rate (ALA to EPA/DHA) is poor.    

 

Okay, so the EPA and DHA are the active ingredients, the omega 3 fatty acids that provide all the benefits. How much should I take? Studies certainly vary but many cardiologists have their patients take a combined 1000 mg EPA/DHA. Please don't get this confused with bottles that read something like Fish Oil 1200 mg. The EPA/DHA amounts are on the label (usually around 400 mg per capsule).

 

Which is more important, DHA or EPA? Wouldn't really worry about it. This is where supplement makers get involved and the gloves usually come off. Studies show DHA is probably a little more "important", however EPA (touted as more effective for inflammation) gets broken down to DHA, just not a terribly efficient process. The standard fish oil has a 12%/18% ratio (DHA/EPA).

 

Should I spend lots of $$ on supplements that have a higher DHA/EPA ratio? That's up to you, but if it were my money - absolutely not. The data is not solid enough for me to recommend that. Buy the cheap stuff.

 

Is the cheap stuff safe enough? Experts say find a label that says 'USP Verified'. The U.S. Pharmacopeia, is a non-governmental standards-setting authority that tests for purity and potency.

 

I eat a lot of fish. If I want the benefits, do I still need fish oil? Long story, but short answer is yes. I hate to keep saying this, but please talk with your doc because it varies for gender and age.  For an average adult without specific risks - a recommendation is about 2 servings of fish/week and many recommendations on fish oil is 3 grams/day (not 3 grams omega-3, but 3 grams fish oil).

 

What about Krill Oil? Ugh. I was afraid you were going to ask that, and I almost made it to the end. I don't know. It appears that there are no downsides, I honestly don't know the price, but not sure at this stage it would be worth what I'm guessing is a higher cost.
