I bought some longer Highland straps for my Jet fins, work a treat, straight from eBay. 30" if I recall, standard was 24".

I have never claimed anything about Polio globally. That post very clearly references "in my country". Your link needs discussion to clarify whatever point you were making, given it wasn't countering any point I made. A student, maybe a decade ago, came to or returned to Australia with Polio and...

The core definition of a vector, if I remember my Despicable Me quotes, is any quantity with direction and magnitude. A vector, which regards to viruses, is how it infects the healthy cell to then take over the cell and reproduce. There appears to be a looser use of the word to also include how...

Eradicate is a strong word, but there is a clear difference between eradicating a virus and eradicating a vector. Polio is one that almost no one in this country in my generation has any personal experience. Yet my parent's generation saw it occasionally among their peers and regularly among...

Dive buddy of mine went to the Fourth Element 3mm semi dry, Proteus II if I recall. He was perfectly happy in that where I was wearing a 5mm wetsuit. His was lighter, easier to don and doff, and only a bit more expensive.

I made no mention of natural 'herd' immunity, where this exists is in local populations. I did suggest an example where local water sources hosts local strains of bacteria. The local population will have immunity, visitors will not, but I wouldn't call that a natural herd immunity. That is not...

When I did DM and OWSI there was no agency requirement to a specific thing, at least that I recall, but the law here requires use of computers for students and dive shop employees. I needed to be competent to teach tables, but personally I didn't use them for diving. The wheel came in the DM...

This is the problem with the idea of visiting a country that has herd immunity. Its simply not beneficial to me that the bulk of the country have immunity if I am susceptible. Herd immunity does not mean you cannot carry and transmit the virus, it just means the bulk of the population do not get...

Yes, G or better. I think the general point here is at that sort of depth, you'll run out of air before you'll run out of time. You've got 56mins at 18m, you'll be cold and bored by 45mins. But as John points out, if you go deeper to start your dive, you max out really quickly, especially the...

Libel someone in a review, expect to be pursued for libel. Truth defence only applies where it is actually true, not where it is your perspective of the truth. Free speech does not mean free of consequence. A prison term is hefty, but it's Thailand. Certainly don't try spitting in Singapore or...

Hand hygiene is more important now than with typhoid, which mainly required hand washing after toileting. And with so many asymptomatic people, what is the likelihood a few more Typhoid Mary characters that refuse to observe basic hygiene. Typhoid Mary's character flaw of lacking concern for...

Any vaccine is going to be tested and effective, but they will all work in different ways and the efficacy will have limitations. Your arm hurting, feeling ill, that indicates your body had a significant reaction to the vaccine. That indicates the DPT vaccine introduced a bacteria that your...

Quote them on it, but until there are multiple vaccines and longer term efficacy studies, they are only committing to reality. You cannot eliminate a mutating virus, but if the S-Spike vaccine works like the inventors suggest it should, the mutations are irrelevant because the virus cannot...

Elimination requires a vaccine, so of course the current strategy is suppression. Given the types of vaccines, the efficacy of different vaccines, and the level of vaccination required for herd immunity, elimination is some distance away. Best case it will eliminate SARS-COV-2 and knock the...

They've also run all the foreign journalists out of town, so its hard to be sure. It is clear the crematoriums in Wuhan were running 24/7 for a few months, they were bringing in workers all over China to run them. The capacity is reported at 5k bodies per day, for something like reported 83k...

Masks are effective like birth control is effective. Effective does not mean it eliminates all likelihood of transmission, it means that it will mitigate some forms of transmission if used correctly. The virus spreads in droplet form, with are comparatively large particles and get captured by...

The shutdown has been six months, let's not blow this out of proportion. In 5yrs time you can speak to the world on how right you were. But otherwise this is a scuba forum and probably all of us have a dilettante understanding of virology and most of us have similar on statistics. The biggest...

She was not allowed to self quarantine and she knew that, explicitly. She knew returning to WA required hotel quarantine and she bypassed that by sneaking back. Self-quarantine, bollocks, she was hiding because she knew the conditions of her permit. She appealed her sentence, she won, the court...

She was not jailed for crossing the WA border, she had a permit to cross the border. She was jailed because of the way she did it. She did not take the flight that she booked herself on, she hid in a truck. When she did not meet the quarantine taxi or police, can't recall, they found here hiding...

Combined cost here would be about $1400, so a major investment, but its going to vary. Its surprising how many OW courses are gifts, so you can be certain those would cease. I don't live in a tourist town, the majority of divers and students are locals. How many OW divers go on to do AOW, those...
