The mineral water expiry date is more about the plastic bottles than the water itself. The bottles contain heavy metals & salts which leach out into the water, tainting it.

How long does fresh orange juice last? If someone had a box of Sainsburys fresh orange juice with a "best before" of March 2015, would it be OK to drink if shaken up to free up all the bits? I know sometimes these dates are a bit short, I recall talk that there's a mineral water than bangs on about being filtered through rocks for thousands of years but has a BB date of a couple of years.

I'd give that a whirl. It might be a bit boozy by now.

Best before: Just ignore.

Thanks all. Not sure whether to try it or not now. Interesting about the bottles though, and the moving water. I suspect the note about the water might have been more a comedic view, like the chap with the unicycle in Chester City centre who used to scoff at people paying £2 for a bottle of Evian, and point out the name should give a clue, as it's "naïve" backwards without the umlaut (or whatever the proper name is) on it.

Are there any rivers that, going downriver, split into two separate streams?

AFAIK the best before dates on bottled water is because of how long the plastic is meant to last and not the water. (im sure someone else can expand)

Diaeresis.

A stream rather than a river, but the most extreme divergence I could find for other examples google "distributaries".

Engine crankshaft bearings.

From watching a video on rebuilding a V8 Cobra engine (very good by the way) I noticed that crankshaft bearings do not have balls or rollers, they are just metal on metal.

Q = why are some bearings metal on metal (and how can they work anyway?) and others have balls and rollers?

Oil pump. Supplies a miniscule coating of oil between metal surfaces through journals. Google it.

Did I need to go to university?

Graduated 11 years ago (Computer Science) and had 4 developer jobs since then, not a single one ever checked that my degree is genuine or called an education reference.

I think I could have crammed everything relevant that I learned into about 4 months of studying at home. Then I could put "PhD at Stanford University" on my CV and started earning a salary 3 years earlier instead of paying to study nonsense.

Difficult one to know there! 1) if you hadn't gone, and the job wanted someone with a degree, then they could have checked and found out you lied?
2) Maybe they wrote to them and you don't know about it?

I've been earning a living in various fields of software development/IT for 34 years. I have a degree in German and Lingustics and have never had any formal education in IT/software development/programming/network support or any of the host of other jobs in the field I've been employed to do.

Odd, innit?

No. Been working in software development for 20 years. Self taught out of college.

We've dismissed a number of people globally for lying about qualifications on CV so it can happen!

All these pet foods that have been launched in recent years with no added this, no added that, basically Health food for dogs (and cats)

Has it resulted in healthier, longer lived, more sprightly pets?

Well my dog's been on healthy option food for a long time and is 17 and a half now. Still running about like an idiot, although a bit Mutt and Jeff. Never imagined she's get to be this old and sprightly.

I've never lied about my qualifications or experience. After over 30 years qualifications are a bit of an irrelevance.

The only times my qualifications have been checked is when required for visa application, however lying on your CV could potentially get you into a lot of bother.

I used to feed my Labrador Orijen, which is 80% meat protein. Proper meat, not gloop manufactured in China. All ingredients are human-grade.
There was no doubt he looked brighter. Everyone commented on his shiny coat and after eating it for about a year he looked like a bodydoggy-builder. Huge muscles, very little fat and endless stamina - he never tired out.
As it turns out, that's not ideal in a pet. Fine for a working dog, but we couldn't keep up with him!

Moved him (and now his "brother") onto Acana, which uses the same human-grade ingredients as Orijen but a lot less protein (same amount as most supermarket dog foods - but the difference is Acana is proper digestible meat protein).
They love it, they're fit and healthy, toilet situation very good/stable. Still endless energy but not quite climbing the walls.

IMO a mid-range food would be good enough. As long as there's no added sugar, not too many crap ingredients, and your dog's not allergic to anything - I doubt he would live longer on a premium food.
But premium foods like Orijen/Acana have no filler ingredients, so although the bags are heavier you feed less and the overall cost is the same as mid-range foods.

Sorry, that doesn't really answer your question. I'll report back in 15 years (hopefully) and let you know how long my dogs lived
