Cancer prevention

I know that is has little to do with computer programming or audio/video editing, but cancer has become a major challenge for today's medical students and professionals, and all people of all ages should be informed about it. We are all waiting for the day in which we open our news portal and find in a huge bold font: "THE CURE FOR CANCER FINALLY FOUND!".

The fact is: it will never happen. Cancer is an extremely complex issue, arriving at the molecular level, down to the DNA, and bellow. All those problems result ultimately in incessant abnormal cell mitosis, therefore tumors are formed, for it to be callable as 'cancer'. In fact, there are many skin cancers and mild superfluous organ cancers that can be cured in a multiple-method approach.

There is a much better way to deal with cancer, though and it is not by curing it, but rather by preventing it.

For that I created this useful image you can share on social networking and e-mail chains.

These are the most useful cancer prevention aids known to date(backed by scientific studies):

• Soursop
• Apricot seed
• Hemp(Cannabis Sativa) oil
• Clean water
• Antioxidants: Pomegranate, Blueberries, blackberries, strawberries, raspberries, Goji, etc.
• Daily exercise
  
  
  

Lesson on Audacity exporting. There is a caveat when exporting your audio, especially if you divided a narration in clips, each clip representing different phrases. This is the original initial vacuum:

Of course, you would assume that vacuum between the time 0 and the start of the clip would be interpreted as silence when exporting. Unfortunately, it does not happen, so the audio is exported as if it started from the beginning of the clip(and not the beginning of the track). To fix this nuisance, allow the selection to snap to the beginning of the clip, and the left side of the selection to snap to the beginning of the track:

Then the silence generator applied to the previous selection yields:

Now if you export the track(by selecting the whole track and clicking on 'export selection'), the audio file will have the initial silence. We can still join the clips(by selecting around the joint and pressing ctrl+j):

To finally have the initial silence and clips fused:
