FYi for those interested. I hope this article posts correctly as I'm forwarding the content using my phone.
I live down near Nai Harn and go swimming there on a regular basis. The lifeguards are young and look very fit and I wonder how well they can swim. I have never seen them train (swim or paddle the rescue board) but have seen them play a bit of beach football and splash about a bit on the board.
Does anyone know what training they have had in order to work as a life guard ?
Why Rip Currents Form
As waves travel from deep to shallow water, they will break near the shoreline. When waves break strongly in some locations and weakly in others, this can cause circulation cells which are seen as rip currents: narrow, fast-moving belts of water traveling offshore. (more info)
Why Rip Currents are Dangerous
Rip currents are the leading surf hazard for all beachgoers. They are particularly dangerous for weak or non-swimmers. Rip current speeds are typically 1-2 feet per second. However, speeds as high as 8 feet per second have been measured--this is faster than an Olympic swimmer can sprint! Thus, rip currents can sweep even the strongest swimmer out to sea.
Over 100 drownings due to rip currents occur every year in the United States. More than 80% of water rescues on surf beaches are due to rip currents.
Rip currents can occur at any surf beach with breaking waves, including the Great Lakes.
When Rip Currents Form
Rip currents can be found on many surf beaches every day. Under most tide and sea conditions the speeds are relatively slow. However, under certain wave, tide, and beach profile conditions the speeds can quickly increase to become dangerous to anyone entering the surf. The strength and speed of a rip current will likely increase as wave height and wave period increase. They are most likely to be dangerous during high surf conditions as the wave height and wave period increase.

Where Rip Currents Form
Rip currents most typically form at low spots or breaks in sandbars, and also near structures such as groins, jetties and piers. Rip currents can be very narrow or extend in widths to hundreds of yards. The seaward pull of rip currents varies: sometimes the rip current ends just beyond the line of breaking waves, but sometimes rip currents continue to push hundreds of yards offshore.

How to Identify Rip Currents
Look for any of these clues:
a channel of churning, choppy water
an area having a notable difference in water color
a line of foam, seaweed, or debris moving steadily seaward
a break in the incoming wave pattern
None, one, or more of the above clues may indicate the presence of rip currents. Rip currents are often not readily or easily identifiable to the average beachgoer. For your safety, be aware of this major surf zone hazard. Polarized sunglasses make it easier to see the rip current clues provided above.

How to Avoid and Survive Rip Currents
Learn how to swim!
Never swim alone.
Be cautious at all times, especially when swimming at unguarded beaches. If in doubt, don’t go out!
Whenever possible, swim at a lifeguard protected beach.
Obey all instructions and orders from lifeguards.
If caught in a rip current, remain calm to conserve energy and think clearly.
Don’t fight the current. Swim out of the current in a direction following the shoreline. When out of the current, swim towards shore.
If you are unable to swim out of the rip current, float or calmly tread water. When out of the current, swim towards shore.
If you are still unable to reach shore, draw attention to yourself: face the shore, wave your arms, and yell for help.
If you see someone in trouble, get help from a lifeguard. If a lifeguard is not available, have someone call 9-1-1 . Throw the rip current victim something that floats and yell instructions on how to escape. Remember, many people drown while trying to save someone else from a rip current.
Rip Current Myth
A rip current is a horizontal current. Rip currents do not pull people under the water–-they pull people away from shore. Drowning deaths occur when people pulled offshore are unable to keep themselves afloat and swim to shore. This may be due to any combination of fear, panic, exhaustion, or lack of swimming skills.
In some regions rip currents are referred to by other, incorrect terms such as rip tides and undertow. We encourage exclusive use of the correct term – rip currents. Use of other terms may confuse people and negatively impact public education efforts.

Joe,,,,
If you don't already know you can use your phone now if you purchase a gevey card. Www.gevey.com. It works well enough but caller id doesn't work 100% correctly.
I'm looking forward to the time when a proper unlock becomes available.

Best pizza I had in Bangkok was from Limoncello restaurant on Sukhumvit soi 11. The "Delizia " was my favorite. If only they made the crust a little thicker it would be perfect.
I'm in phuket now , any suggestions for a top quality pizza down here?

Guess they will have to rename it "Not the Pizza Company"
haha..
but there pizza'a are a disgrace, taste horrible !! and for the price they charge you can go to an Italian restaurant and get a ' real ' pizza .............
Now, everyones got to try that yummy one you can get at the Chiangmai zoo. It has weiners and manayonaise..mmmm mm..
what a treat that one was. I never ever found a decent REAL pizza even in the pizza huts around Thailand. It is a disgrace of a pizza for sure.....nothing what it should be or taste like................it's round is about it!!...

My suggestion is after you collect your bags and are leaving the baggage area do not stop to have your bags x-rayed,
just walk straight past any personnel that may be there and don't look at them. They have never stopped me.

I have a pinched nerve in my neck and may need spinal surgery to fix it. I'd like to find the best place in Thailand to have this done.

Hi Chris,
I take it that you are trying conservative treatment before you're considering surgery. Have you had treatment, an MRI?

Hello Gentleman,
One year now in BKK and I recently purchased a Er6n from Karat and they delivered it to my BKK condo no charge! Possibly an option to waiting 3 months on the Rama 9 list.

I don't have time to read through this tread now but I'm interested in doing some bike mods and connecting with others for some rides out of town.

buying new pick up
in Thailand Motor Discussion
Posted
I have been searching many sources and spending way too much time looking at thai language only company websites.
Any helpful input is much appreciated,,,
I live in Phuket and am interested in buying either a 4 door pick up or an suv.
Undecided about 4x2 or 4x4. Not sure if there are many places near phuket where I can enjoy using 4x4?
Diesel, I assume for the lower cost. Also curious about future availability to run bio diesel as it becomes available.
Used for mainly communing to work 5 days/week, weekend ocean sport gear, road trips and will not use for heavy hauling.
Would like the best handling AT available. I suspect a pick up loaded or unloaded will not handle as well as an suv?
mitsubishi pajero sport vs pickup up?
vs Toyota vs ?
under 1.2m Baht
Cheers,,,,
