Monthly Self-Portrait, April

So what to do for this month’s self-portrait, especially as I have this damned filthy cold back again? Oh well, lets have something some may consider TMI – although it’s nothing you couldn’t safely see in the gym changing room.

As long-time readers may remember, I’ve said on a number of occasions that I have a secondary nipple. This is apparently not that unusual – I bet some of you have too. It’s on the right side of my abdomen, a bit above the level of the navel. The corresponding place on the left side has just a slightly denser area of hair.

Anyway this is what it looks like, fairly close up. On the left is the actual vestigial nipple. On the right, a mole. (I’ve always had the mole; it’s nothing to worry about). Keep in mind that the area in the photograph is about 4cm wide.

First it seems there may be evolutionary advantages to the affliction of “teenage brain“. [£££]
Secondly apparently puberty triggers “teenage armpit odour” of cheese, goat and urine.

Now to something more wholesome … Every cat has a strange pouch under its belly and scientists still don’t know why.

Monthly Links

Welcome to our monthly collection of links to items you may have missed but which struck me as interesting or amusing. We’ve got quite a collection this month, and as usual we’ll start with the hard stuff – the science – and then it’s all downhill.


Science, Technology, Natural World

Let’s start with something topical … So just why do we have leap years? [££££]

On Earth, but not entirely disconnected, scientists have concluded that the largest volcanic eruption in recorded history happened 7300 years ago off Japan. [££££]

Changing tack entirely … Researchers have worked out a more detailed mechanism by which erections work – at least in mice – opening the door for better drugs for erectile dysfunction.

Which somehow brings us to penguins … One of the current team at UKAHT’s Port Lockroy station in Antarctica describes counting penguins and why the penguins think pebbles are cool.

So why do birds have skinny legs? [££££]

Let’s hear it for the Yellow-Crested Helmetshrike (below), which has been rediscovered after not being seen for 20 years.

February Quiz Answers

Here are the answers to this month’s five quiz questions. If in doubt, all should be able to be easily verified online.

Medicine

  1. Where in the human body would you find the medulla oblongata?  The brain
  2. If you have cryophobia, what are you afraid of?  Ice or cold
  3. What is the largest organ of the human body?  The skin
  4. Which is the only body part that is fully grown from birth?  Eyes
  5. Where is the strongest human muscle located?  Jaw

Answers were correct when questions were compiled in late 2023.

On Depression – X

Another in my very occasional series of articles on depression – my depression. They are written from a very personal perspective; they are my views of how I see things working and what it feels like on the inside. Your views and experiences may be vastly different. My views and experiences are not necessarily backed by scientific evidence or current medical opinion. These articles are not medical advice or treatment pathways. If you think you have a problem then you should talk to your primary care physician.


I recently came across the following elsewhere on social media.

One of the worst things about depression is that it’s a self-reinforcing cycle. In many ways, a lot of the popular “mindfulness” or “yoga” or “touch grass” or “diet and exercise” things about recovering from depression is a correlation, not causation thing which is a reversal of cause and effect. When you’re depressed, you CAN’T do the things that help you not be depressed, or at least you can’t sustain doing them for long because they drain more energy than they’re returning.

It’s a lot of feel good “pull yourself up by your bootstraps” nonsense. When you’re depressed, even when you try to force yourself to do the endorphin generating activities, your brain is so full of depression juice that it sucks up all the endorphins you might have gotten otherwise. So now you’re just even more exhausted from trying to do the thing, and have even more depression juice in your brain because you tried to do the thing and didn’t feel any better, which must just be because you’re a broken failure.

[Jess, @JessTheUnstill@infosec.exchange at https://infosec.exchange/@JessTheUnstill/111880212752583330]

I don’t really agree with the final phrase about being a “broken failure”. I’m a broken failure only in terms of getting rid of the depression and in consequence having fucked up too many things in my life. And who’s surprised after 50+ years experience – we’ve trained so long and hard that we’re now experts! Otherwise this is a pretty spot on summary of how my depression seems to work.

Medics please note that this is how depression works for many of us, so don’t be surprised when we tell you that all your suggested fixes don’t work for us.

February Quiz Questions

Each month we’re posing five pub quiz style questions, with a different subject each month. As before, they’re not difficult, but it is unlikely everyone will know all the answers – so hopefully you’ll learn something new, as well as having a bit of fun.

Medicine

  1. Where in the human body would you find the medulla oblongata?
  2. If you have cryophobia, what are you afraid of?
  3. What is the largest organ of the human body?
  4. Which is the only body part that is fully grown from birth?
  5. Where is the strongest human muscle located?

Answers will be posted in 2 weeks time.
