Just speaking to the economics and leaving the politics to Facebook, there is a reason that so many products are manufactured in China. That reason is actually two fold: (1) because the Chinese have access to a vast resource of cheap labour, which is no longer the case in the USA or Europe and...

I always tried to ignore it. In all the time I gave lessons I became friends with a number of students but romance was never really in the cards. I had one student who I believe fell in love with me (long story but I trained her for an entire season until my wife started to object to her...

Get up early. Go jogging before your work and before it gets hot. Getting up early only sucks the first few times. After that it starts to feel good. R..

John, given this response, in your case I would say that it only comes down to a matter of age. Keep yourself healthy and fit and then age doesn't matter. Some operators still won't want you because you're not "attractive" enough to their target clientele but there are many out there who...

John, In principle I think being older has some distinct advantages and disadvantages. The main advantage is life experience. The main disadvantage is physical endurance and looking older, which some employers won't want. Can you do it at that age? Yes. Should you want to? No so sure...

Sad news, Don. My sincere condolences. R..

Well that's a good point. In every profession there are some incompetent people, from police to politicians, from professors to priests... and yes, some carpenters and some regulator techs. Normally the industry will filter them out but it doesn't always work that way. My conviction...

To be clear, I am not a doctor but I am a (retired) diving instructor. A feeling of being short of breath is not uncommon among new divers, particularly when stress is involved. My guess is that being specifically instructed on how to relax and breathe normally may help it clear up. If you...

As for the Apeks ATX 200. It's a perfectly good regulator, provided that it has been well maintained. Being "older" does not necessarily make something "worse". This particular regulator was top-shelf in its day and will still suffice for any application you can think of.... .again, provided...

This is the only question you asked so let me address that. The difference in skill level between myself -- someone who can find the one hammer I have in the house after searching for a while -- and an actual carpenter -- who sleeps with his/her hammer under their pillow -- is tremendous. In...

CESA's are a specific issue that I would characterize as an occupational hazard. The hazard can, however, be managed to some degree. (a) you don't need to do CESA's with all of your students on the same dive (b) you can choose to do the CESA's at the beginning of the dive as opposed to...

35 years of diving, of which coming on 20 years of technical diving and I've never been hit. Part of the reason why I think this is the case is because I have a thorough understanding of decompression theory and I put effort into keeping current. Yes, although it can also be considered an...

Disclaimer: I am not a doctor, just a long time diver and a former diving instructor. It doesn't sound to me like an injury and it will more likely than not clear up on its own. However, I would recommend having your GP look at it if for no other reason to get a better understanding of why it...

Not at all. Function before form, of course, but if all things are equal than showing a little originality won't be held against you. (except in certain circles, and even in those circles the rigidity is slowly diminishing over time). R..

I agree that it isn't really a deep investment, but the price is still 20 times more per tie wrap than the exact same product if you bought it online in a larger quantity. Obviously it's not about the money but the fact that some bozo bought a bunch of tie-wraps bulk, repackaged them with no...

Scuba specific ties? If they even exist then they are the same zip-ties you buy at the hardware store but in a different package and with a lot higher price tag. Just don't use ones that are too big or you will feel the cinching block with your lip. Also the way you secure it should have...

I think it is a credit to the inventor of the red/white diagonal flag that they saw a need and thought of something that fit that need perfectly. Obviously, it's an American invention and these days it's not fashionable to consider Americans as trend setters, but when this flag was developed...

Just goes to show you that you can never stop "sharpening the saw".

... incidentally, I needed to look up this equation because although we all learned it during our EAN class the only thing that is really relevant to diving outside of a technical context is that you know how to enter the EAN % in your computer. Even for technical dives we use software that...
