The grenade thing depends on the generation of grenade. Also depends on the country of origin. Assuming we are talking about the American M67 one you see in most movies, there are 3 different generations of safeties.

Quick basics of an American grenade- the spoon is the handle looking thing that is sticking out the top and runs along the side. Under it in the head of the grenade is a spring that is always trying to push the spoon off its hinge and make it fly off, while then starting the fuse and the whole bang process. The safety pin (a codder pin with a ring on one side to pull on) runs through the head of the spoon and is held in place simply through binding into its hole/channel by tension provided by the spring. For a little bit of extra safety the end of the pin sticks out about a quarter inch and is bent for a little, but easily straightened and pulled out with the ring (look up a picture and you will see what mean).

The old ones were just the safety pin held in place by the spring/spoon mechanism. But if you had excessive vibration or just enough pressure and you had pre-straightened the safety for pulling ease, it would negate the spring pressure and the safety pin could slip in and out with ease (thus easy to pull with teeth for Rambo effect). People didn't trust it, so it was typical to then use electrical tape to hold the spoon down wrapped around the full body and then a bit extra folded back to make a quick pull tab. To throw: pull e-tape, pull pin, throw. The army then added a secondary safety to the safety. It was this secondary safety clip that held the spoon down to the head, providing constant tension and stopping the vibration loosening issues. They were also intentionally designed to have to get pulled off in opposite directions. To throw: (I am left handed) sweep safety clip left, pull pin right, throw. This was in my opinion the best setup and my favorite of grenade generations. Apparently this was about 50/50 with other others. So the army then came out with their third generation, the "confidence" thumb guard thing. It is a metal flap switch that locks/latches the safety clip onto the pin ring. I thought it was dumb. Most people hate it. But credit where credit due- it is impossible to fuck it up. Now to throw: thumb/sweep up on confidence latch, sweep left on safety clip, pull right on pin, throw.

I am a fan of all good sci-fi, regardless of the time it was made or the limits of the budget. This one is on the list. I will warn others as it has been pointed out- very rape centric plot and story beats. Be sure to watch it with a good level of suspension of disbelief and understanding of the setting. Beyond that, it is one of the best post apocalyptic stories out there and I wish it was redone with more plot, tighter story, and less rape related with the exception of the Topeka plot line. Highly recommend for anyone who enjoys old sci fi or post apoc.

You would be surprised. If you worked a decent job early in life, moved up the ladder, retired as upper middle class making $250k-ish, it is kind of expected to have about 2-3 mil in your retirement. Hell, if you work a half way decent government job and invested wisely your entire life and didn't have stupid amounts of debt, you should have about a mil in retirement.

1 mil in retirement gives you about 5,500 per month at a growth rate of 6%, withdraw rate of 3%, and annual inflation at 3%. The current recommended retirement is a little under a mil.

As far as retirement funds counting as tradable assets, that is how your 401k accounts work. It is literally a stock market account. The question comes down to when the tax is paid, pre or post withdrawal. In a roth IRA you pay the tax coming in. In a traditional IRA you pay tax when the money comes out. Either way, as long as the money stays in the account you can make it liquid, put it in a stock, bond, mutual fund, whatever you want as long as the account can do it; but in the end it is in a trading account and short of the cash in there, it is a tradable asset.

Biggest argument people are going to have against this is reading the headline and then realizing most their retirement is in the form of unrealized gains. But if you then just read the qualifier of $100 million, you will quickly realize we are not talking about normal people here. We aren't even talking about normal rich people. We are talking about the 1% of 1% people.

I think they left out the most obvious questions-

Are you super rich?

Can you afford elective heath operations that will potentially prevent life ending illnesses or affliction?

Can you afford expensive lifestyles tailored for your health?

Can you afford to reduce all forms of stress in your life and live with no worries?

Congenital? No. Acquired? Yes. The area of the brain that processes and interprets sound has to develop. Without sound input as a child, that won't happen.

Current leading theory of tinnitus is called the 'central gain' theory. This is where the brain becomes accustomed to seeing signals from the ear at a certain level, and when that neural level is no longer at that level it will add in its own noise to make up the difference. This noise is then perceived as a tone or sometimes a broadband sound, commonly described as either a ringing or a whooshing sound. Sometimes it can also be described as crickets. Depends on the person and cause. Not all hearing loss comes with tinnitus, but most tinnitus comes with hearing loss. In audiology school we had a whole class on tinnitus and covered many interesting aspects exactly like your shower thought here and went over papers on every angle you could think of. It was fun. But in the end, the brain has to at a minimum know what sound is to even perceive sound.

Yeah, colon/anal cancer will do this as well.

He needs a doctor, and fast. Best case scenario it is ulcerative collitis. Worst case he is getting an MRI of his brain and brainstem to find out it is a central tumor and will only be getting worse.

While China is quickly becoming a global leader in clean energy adoption, it still has some work to do. The nation still relies heavily on coal-fired power plants and will need to retire those facilities in favor of more sustainable options in order to truly offset its CO2 emissions.

This is a bit of an understatement. China leads the world in both renewable energy usage AND coal use. And by a lot. Then they also lead in steel production with older blast and coke furnaces that are super CO2 intensive. And in concrete production and use, also super CO2 intensive.

I'm not trying to shit on the progress they have made. It is nice to see them taking this more serious than some others. But this article kind of green washes their energy, overplaying their renewables and not even mentioning their dirty power.

In the army we called that lube the whale sperm. I'm not even joking. It is called LSA, and the cold weather one is LSA-T. But when you have a bunch of young 20's infantry guys we just called it the whale sperm.

Fun fact, in the book Jurassic Park and in the initial script, there was a river boat sequence. It was extensively planned in preproduction and teased as part of the plot. This was spread to the other 'tie-in' merchandise and park ride. This is why the universal studio ride is a water ride and why games that timed their release with the movie had river sequences. But as we all from the future know, it never happened. Budget overruns and shooting delays lead to script rewrites to cut out that sequence.

Not a coincidence. If you look at the flash/recoil compensator it looks like a classic 3 way with the tearing starting on the openings.
