Previously, ppl like to ask you. If mum and wife drop into the sea, neither can swim, who do you save first. But from what I sees, it's all goes down to the age. If you were young, your thinking/answer will be mum, cause wife can find another one. When you are older, you will think of wife, cause mum old age, after saving her, it might be a waste and furthermore, if your family got kids, wife more impt than mum.
I just think of this. What if, your wife, dropped into a river while you 2 are crossing and you are having a DSLR with you. Will you risk your DSLR, dump it aside and save your wife? The river water are fast in pace and you know your wife surviving rate is low. But the DSLR containing a lot of the photos of you and wife during the trip. Your DSLR might be pick up by someone and before you return to that spot. So, what is your choice?
