It is, with me sometimes answers tend to be long, for it is needed to explain some stuff, and don't mind me saying it but You seem a bit confused about it all, it is a matter of truth and lies, not a matter of belief, men have never been into space, it is physically impossible, and You don't need to question NASA but at the same time You can't say that You truly enjoy space since most of the lies, if not all, about space and how it functions come from them and their priests..

And it's good that You do a lot of "crazy" thinking, but at least do it based on truth not in cognitive dissonance or programmed views of the world and space =/

Again, it is impossible to live on Mars, we don't even know what it is truly, and we can't get there, so any question about living on it becomes a non sequitur, but entertaining Your line of thought I'll answer that for You..

IF it was possible to live on Mars, life span would differ based on the breathable oxygen available, more or less oxygen would probably shorten life time, in the case of less O₂ the body would have to exhaust itself to survive with lower levels of O₂, while on the contrary with higher levels of O₂ it would be intoxicated or age at a much higher pace, also temperature would have a fair share of importance to that matter.

About the time question, time is not a force, it is a construct and it is the same here or anywhere else, there is no time-space as such so, no ageing faster or slower, firstly because we can't go to Mars, and secondly because time is a construct of the priests at NASA.

What You said about watching the Moon in the morning when the Sun is rising, I fully agree that is a magnificent scenery, very beautiful and enjoyable, one of those where one can find a nice work of the Creator of all and everything.

The P900 is indeed an awesome super zoom cam, my favourite one, the P1000 is also cool but I remember checking the specifications and there was something back then that threw me off, made me stick with the opinion the P900 is my favourite, and since I can't get neither for now I'll let it be as is until possible =))

Have an awesome day, all the best,
