Answer:
Natural factors of population change can't be swayed by humans. So for an example of a natural factor take an Earthquake. As of right now we can only predict when Earthquakes will. Inevitably some things will still get damaged and that just can't be helped. An Artificial factor for population change is something specifically made by humans. For an example take a genocide. If some guy decides he wants to go on a killing spree, well all I can say is that is Definitely not natural. Hope that helped.
Location- If a place is too far away, it may be extremely difficult to even keep the motivation to go.
Cleanliness- You DO NOT want to work out in an area that is unsafe or unclean because it speaks volumes about what the rest of the gym staff is like.
Price- You need to be able to afford where you are going to be able to go. A place that is too cheap may not meet your needs and a gym that is too expensive can break the bank if you are not consistent or do not need the extra cost.
Well i would say awesome but Edward de Bono (i have no idea who he is) said an expert is someone who has succeeded in making decisions.
Sorry if it is confusing.
Hope this helps :)
I guess Lifelong Memories is the answer.
