Lifestyle: taurine, part 1

Going online for self-tutoring about energy drinks, the tutor follows the leads as they come: more about taurine.

In yesterday’s post I began about taurine and reported that two sources suggest 3000mg per day, in most cases, is thought to be safe–I’m sure that’s for an adult.

Why is taurine in energy drinks, anyway? What possible benefit might it convey?

Supposedly, taurine (within safe dosage, of course) can offer the following benefits:

  1. Taurine can decrease anxiety.
  2. Taurine can promote fat burning.
  3. Taurine can increase insulin sensitivity.
  4. Taurine can elevate testosterone.
  5. Taurine is an antioxidant.
  6. Taurine can increase exercise performance, and may also help recovery.
  7. Taurine can help lower blood pressure.
  8. Taurine, with magnesium, can promote better sleep.
  9. Taurine, with caffeine, can enhance mental performance.

I suspect that several of the benefits above are not typically what people imagine when they reach for energy drinks.

Lifestyle: taurine, part 0

Lifestyle means constant self-tutoring. The tutor begins research about taurine.

I was talking to a student the other day who consumes energy drinks. She mentioned they can be controversial, so I asked why. The caffeine and taurine content, she answered, are two points of concern.

Compared to a cup of coffee, her drink seemed to have about 50% more caffeine. The taurine was around 1500mg; I don’t remember exactly.

I’m no one to give lifestyle advice, but I drink two pots of coffee per day. The caffeine content, therefore, did not give me pause. The taurine I’m much less familiar with, so did some preliminary research today.

Two sources I visited say that taurine, up to 3000mg per day, can be considered safe. (I assume that’s for an adult, of course.)

So, if one can contains over 1500mg taurine, then perhaps two cans per day is not suggested.

I’ll be talking more about taurine, caffeine, and energy drinks.

Lifestyle, mobile phones: phone cases

Perhaps lifestyle requires more tutoring than anything else – for me, anyway. The tutor relays his experience phone case shopping.

Yesterday I got schooled on how to buy phone cases. I’m interested to share what I’ve learned.

We bought my son a phone that’s been out a couple of months. It’s an Android, a very good phone, but not flashy or brandy.

At a big-box store the clerk told us that, with more generic phones, cases are easier to get from a dedicated phone case seller. The big box places might stock cases for prominent brands and makes, but there are many others that they might not cover very strongly.

Therefore, we went to a kiosk in the Woodgrove Centre mall in search of a case for my son’s new phone. The kiosk is near Boathouse. We didn’t even have his phone with us – no problem. The attendant knew which one it was, and that it had been out for only two months. He had a few choices, including wallets. He also had screen protectors.

I chose a wallet case for my son’s phone, and also got him the screen protector. The attendant wanted to put the screen protector on for us, and told us if we brought him the phone, he would.

Just for kicks and giggles, we asked if he had a case for my phone – a Nexus 4. “Nexus 4?” he repeated. He uncovered a storage box, dug in, and pulled one out. I bought it. Here is my Nexus 4, in its new amazing case:

Lifestyle, CSS: colours: what is the colour ochre?

Colour discovery means constant self-tutoring. The tutor shares a find about ochre.

I’ve always thought ochre meant red; apparently, I thought wrong. It turns out that ochre is an orange color, leaning brown and yellow rather than red:

Lifestyle: what is the most visible colour?

Sometimes, during tutoring, the key is to ask the really interesting questions, whatever the topic. The tutor brings up one he recently wondered.

What is the most noticeable colour, by day, anyway? Red? White? Apparently neither, but rather, fluorescent green/yellow. Perhaps it’s no surprise you see it on reflective tape and even fire trucks and hydrants.

Apparently the human eye is particularly tuned to that green/yellow colour we think of as fluorescent green (or yellow). Hence, its adoption.

For night visibility, the opinion is divided – more on that in a coming post:)

Lifestyle: the Tenlined June Beetle

Meet my latest visitor: a tenlined June beetle.

I never see many of these around; this is the second I’ve seen this year. They’re meant to live west of the Rocky Mountains, so I’m pretty sure of this I.D.

Lifestyle: watering the lawn: best time and way

I’ve recently taken self-tutoring about lawn watering. The tutor shares some discoveries.

On the west coast, summer is often very dry. Typically, if the lawn isn’t watered, it will go brown.

Where I live, we have watering restrictions. On the days I’m allowed to water, it’s either 5-9am or 7-10pm. I looked up when is better. Condensed, here are the hints I found about watering the lawn:

  1. Water in the morning before the heat of the day.
  2. Use a pulsating sprinkler: the water spends less time in the air → less loss to evaporation. However, for new grass,
    use oscillating sprinkler → gentler on the budding seeds.
  3. Water to soak 6 inches (15cm) deep.
  4. Water no more than twice per week.

I don’t water every part of the lawn every time; sometimes I only water the weaker patches, maybe for twenty minutes each.

Lifestyle, biology: A twin-spotted sphinx moth?

I find that being outside in the summertime leads to constant self-tutoring. The tutor shares a find from the siding this morning: a twin-spotted sphinx moth (Smerinthus jamaicensis)

I don’t remember seeing one of these. A quick internet search yielded what I believe is a match. Indeed, Smerinthus jamaicensis is meant to live in southern BC: I think that’s what this handsome moth is. (I didn’t disturb it; it seems to be fine with the paparazzi:)

Biology, Lifestyle: food preservation by irradiation

Tutoring biology, you might be asked about food irradiation. The tutor briefly talks about it.

Food irradiation is a preservation method that exposes food to radiation to kill organisms that might cause spoilage.

A question I had was, “Why doesn’t irradiation damage the nutrients in food?” From reading, I’ve surmised that the radiation separates the organisms’ DNA into building blocks, rendering it useless (so that they mostly die or just can’t reproduce). However, those building blocks are still useful as raw materials to whoever consumes the food – that’s as I understand, anyway.

Food irradiation has been an accepted technique for decades; the US space program has used irradiated food since the 1970s.

Grapes to raisins: the condensation ratio

Tutoring math, all kinds of relationships might call out to you. The tutor brings up the water loss from grape to raisin.

According to one source, fresh grapes contain 1g fibre per 138g. According to another source, raisins contain 1g fibre per 40g.

Therefore, assuming the only loss from grape to raisin is water, 98g of 138g is lost as grapes become raisins. The percentage weight loss is 98/138 = 71%.

Neat, eh?
