Mental health problem rates

Interestingly, the Defense Minster indicates that for the years 2011 to 2013, about 500 males a year are exempted from National Service due to mental health issues (link). Checking the statistics for live birth in Singapore, we see that we typically have slightly less than 50,000 births a year for the period of 1990 to 1995 (link) which is probably about the time these guys were born. Given that the gender ratio is Singapore is pretty close to 1:1, we can probably assume that the rate of males having mental health issues is 1 in 50.

Assuming that mental healthy issues are equally distributed among males and females, this would mean a rate of 1 in 50 for the general population. That does seem higher than would be expected. So a bit of googling shows that the rates in the US has been estimated to be 26.2% which is far higher than 1:50 (link). Of course one of the issues is the definition of mental health issues here, the one used in the US is any form of mental health issue while the one reported in Singapore is mental health issues severe enough to be exempted from National Service. But nevertheless, it does appear that mental health issues are far high in frequency than I would have suspected.


Due to the renovations going on, the site was down for a couple of days. They needed to take away my current table so I had no place for the computers till that spot was cleared. Well it is back online now and that is good.

The renovations have been happening for a week and more now. The entire house is like a war zone. Since the cupboards are being replaced, all the stuff inside is littered all over the house.

Just two more sets of cupboards left and then a couple more minor things. So it should be over soon.

East coast park

The family was at East Coast Park prawning. I am not a prawning person so I walked over to the beach to take some photos.

The following is a panorama done by taking 38 images hand held and then stitching it together in Autopano Giga. I must admit that Autopano Giga makes it so simple. The final image is about 90M pixel in size which is huge.

The following is a HDR done in Nik HDR Efex Pro 2 which I like for its more realistic look.




We got a Panasonic GX7 for Esther as she was very interested in photography. When we were at the Gardens by the Bay, she was full of energy taking photos.

The Olympus compact that she was using does not really produce very small images.

Using the GX7 brings back memories of the GX1. It handles great, very fast in all operations. Autofocus is fast and accurate. And the interface and buttons are in my opinion better than the EM5. And without the EVF bump at the top, a lot easier to get it in and out of the bag. So in general it is a joy to use.

The images are comparable to the olympus so no surprises there.

Will probably need to shoot more with it before I form a final opinion, but the initial feeling has been good.

My m43 lenses

Here are the lenses which I have right now together with the filter sizes for ease of my own reference.

  1. Olympus 12-40mm F2.8 62mm
  2. Panasonic 14-140mm F4-5.8 62mm
  3. Panasonic 20mm F1.7 46mm
  4. Panasonic 25mm F1.4 46mm
  5. Olympus 60mm F2.8 46mm
  6. Olympus 75-300mm F4.8-6.7 II 58mm

Not too bad, just three sizes.
