The Bible doesn't really tell you to do anything extraordinary because of the nearness of the end. Those who died in the "so-called" deluge are described as doing ordinary and necessary things. Their only mistake is that they "took no notice".
Taking "notice" or being alert is a good idea for people who want to plan things and even invest. What's the harm with keeping an eye on geo-politics, the environment etc. Finally the Bible says that an event will occur which will be a sign that it is time to flee to safety. What's wrong with looking at the possibilities? It's up to some organized group of "holy-ones" to identify the "disgusting thing that causes desolation standing in a holy place" and give instructions to flee from somewhere (maybe the USA) to somewhere else (who knows?).
If this doesn't happen you live an observant life. If it does happen and you get some kind of benefit (salvation? Long term or temporary) consider yourself lucky.
I grew up as a JW also. I was born a month before Hiroshima. I lived my youth afraid of the Soviets, like most 50's kids. But as a JW I carried the horrible burden and nightmare of being separated from my parents and subjected to unimaginable torture during the final assault of Gog of Magog.
I definitely am working on retirement. (Probably a cardboard box at fisherman's wharf in SF). And I am still "taking note". Who knows?
