The female “KISS” for desire

Did you know that among animals, especially rodents like mice and rats, the females decide when they are ready for some action? You know what I mean … wink, wink. That’s right, the female rodents decide when, and with which male, they want to mate to produce offspring. And this decision is made with the help of a particular type of neuron in the brain that is essential for maintaining fertility, called kisspeptin.

Thus, unlike in humans, the need for mating is prompted in most mammals only around the time of ovulation. This ensures the highest chance of fertilisation. Particularly in rodents, the female controls the initiation and timing of copulatory contacts with the male, triggering the mate preference and sexual motivation circuit in their brains. However, what controls the neural circuitry to drive the female rodents to be suddenly sexually receptive to the males, in comparison to when they are not, remains elusive. An international team of researchers led by Dr Julie Bakker from GIGA Neurosciences, University of Liege, Belgium in 2018 may have some answers to this intriguing question.

From bitterness to gratitude

That first run was dreadful. I imagine I looked like Bigfoot, captured on that famous grainy video taken in the 1960s. I felt heavy, ungainly and uncoordinated. I was so embarrassed I used to get up at dawn so no one would see me stumbling along. For the first two months I could barely run, my back and feet hurt, and at times I collapsed onto the ground sobbing because the target of running five kilometres seemed an impossible dream. But every day I picked myself up – mentally, physically and emotionally – and continued to put one step in front of the other.

I remembered those days recently as I stood catching my breath after skiing to the far end of a high alpine plateau, immersed in the visual splendour of the winter playground, which stretched as far as I could see. I pondered my journey from the rolling hills of lowland England to the peaks and lakes of Southern New Zealand. The journey took me from being a competitive national rower in my teens, through being hospitalised and barely able to move, to regaining my health and becoming an engaged Dad sharing my love of outdoor pursuits with my children.

Still reading: turning the pages for health and wellbeing in teens

This digital world has a few tricks. It’s fast, lightning quick, bringing rewards with a few quick clicks. We skim and skip, casting for the tantalising bits. And if it ain’t got us hooked real quick, we give it the flick.

And this is the world where a large number of our teens are experiencing the only reading they will commit to for pleasure.

There is much to be lost if we give up on the idea that reading deeply matters. We need to make sure our young people find the time to be still, and to ensure they are still reading. We risk a lot if we stop fostering a culture where deep reading matters.

A loaded skip: moving in a pandemic

In the past ten months, my husband, his sister, and I have moved my husband’s parents – first one, and then the other – into different wings of the same managed aged-care facility. We then had to sell their Northland home, built by my in-laws and only reluctantly abandoned after fifty-five years of married life. When settlement finally eventuated, we had a few frantic days to travel to Northland and clear out the house. All this has occurred during the 2020 Covid-19 pandemic. My husband’s job at Auckland Airport dictated strictly no close contact with either his father or his sister (as she was helping their father move into the retirement village). Auckland’s second lock-down was announced three days into the final push, my husband was recalled to work, and the whole thing ended in a terrific rush.

Having moved my own mother out of her home just before she died eighteen years ago, I know this is never an easy process for any family. Then, however, I didn’t have to wear PPE and masks, stay in motels, and refrain from hugging my parent when she was most distressed. I didn’t move my mother with any notion of not being allowed to visit her again, or aware that I’d be expressly excluded from attending her funeral. These were all realities my husband faced, and faces, with regard to both his parents in these uncertain times. Covid-19 has certainly added some unkind twists to all of our everyday situations.

Many people think of the hospice as a place where people with cancer go to die. Back in 2014, when I frequently walked past the Otago Community Hospice building in Dunedin’s North East Valley on my way home, that was my impression. What a sad place that must be to work, I thought. Although I practically lived on its doorstep, I had only ventured into this daunting place once. My partner had asked me to drop off a gift to a friend who was a hospice inpatient. I agreed, but only to leave it at reception. I didn’t want to go any further, in case I encountered dying people.

Like most people, despite ‘bearing witness’ to thousands upon thousands of deaths (both real and imagined) through images in the news and in film and television, my exposure to the reality of death and the dying process was minimal. When I went to the funeral home to view my father’s body in 2003, I was so uncomfortable about real death that I could only manage to look at him for a matter of seconds. When my mother had a serious stroke a few years later, I spent time with her as she slowly deteriorated, surrounded by her children, grandchildren and extended family. I was not present when she died, but when asked if I wanted to see her body, I declined, remembering how traumatic I had found trying to view my father’s body years earlier.

Are we there yet? On the exercise of patience

Patience (n.): the calm endurance of pain of any provocation; perseverance; forbearance; quiet and self-possessed waiting for something.”

Okay, that’s nice, but are we there yet?

Patience is a virtue, so the saying goes, but I disagree. Yes, it’s possible to have the patience of a saint, but it’s also possible to have the patience of the devil. Many crimes and abuses have been committed by people patient enough to wait, preparing all the while to strike. Aggressors against others are often very, very patient. For the victims of those aggressive or oppressive acts there is more wisdom than virtue in ensuring your survival by keeping your head below the parapet and biding your time. Patience is a strategy, a behaviour, a matter of judgement, of choice-in-circumstance. Just as courage is called out only in the existence of fear, patience comes into existence in the presence of, and in response to, impatience. It requires the exercise of personal restraint and impulse control in the service of a greater end goal, and it may feel entirely counter-intuitive in the moment. I hesitate to disagree with my trusty Collins Dictionary, but it may not feel anything like “calm endurance” or “quiet and self-possessed waiting.” Yes, the patient person waits, but it’s an active state involving paying attention, reflecting, planning. Patience isn’t a thing. It’s a capacity, an attitude. It’s an ongoing recallibration of approach rather than a one-size-fits-all solution. It’s a work in progress, a practice, an art.

Yes, yes, so you say, but are we there yet?
