It has been a journey filled with mountains, valleys, rivers, and seas.

Growing up a top achiever, I thought life would be smooth sailing, but like most of us, my first rude awakening came when I lost my mother in 2010. I had to learn to rely on myself and others to keep my head above water. I ask for help when I need it, so I use the services of professionals from time to time.
 
One of the most valuable tools I use, is my gift of singing. I call it my cup filler. I have songs for every mood. I have playlists of songs that I sing along to, pieces that help me balance.
   
I have learnt over the years that I need fuel just like a car needs energy. Moreover, a vehicle needs more than just fuel to function efficiently. I apply the same metaphor to my mental well-being. Besides music, I fuel myself up by doing good to others. 

I love spending time with my dogs, and they know how to make me smile without saying much. I have recently started reflective journaling, and I find it very useful to interrogate thoughts that are not healthy for me. Overall, I remind myself that I am not perfect, and that life is about balance. 

When the scale starts tipping to the one side, life will always calibrate itself into balance, and sometimes those calibration moments are when I feel stressed and overwhelmed. Mine is not to go into panic mode, but to work with life towards achieving that balance again. Over the years, I have noted that this process is a never-ending one.

Scientists discover a water reservoir beneath the Free State
2009-12-09

Dr Holger Sommer

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
