Well, mate, let me tell you this: Privacy is a myth in the 21st century. But jest aside, if you’re concerned about the digital footprint, you could use a VPN service on your phone too. Many reliable ones out there. However, bear in mind that while VPN encrypts your data and hides your location, it’s not bulletproof. Apps like Google invariably end up tracking data but if you’re not doing anything illegal or something you don’t want to haunt you, you should be fine. Although I must add, the idea of uninstalling work apps sounds pretty extreme and cumbersome. Not to mention, it kinda defeats the purpose of being a digital nomad, doesn’t it? We’re all about travel and work coexisting, not one at the expense of the other. So, weigh in the practicality against paranoia before diving in the deep end of the anonymity pool.

Amidst this hailstorm of career trajectories, I would say check out the data analytics field. Being mathematics graduate, you might already have the necessary skills, and it’s a field that will continue to grow as companies realize the substantial benefits of analyzing their data to make informed decisions. However, it’s not always easy and glamorous; you may have to start from scratch and learn different programming languages and tools.

This being a digital nomad forum, I suppose you are interested in remote work, right? Well, the only caveat here is that your location might limit the remote opportunities available to you; most companies look for local remote employees because of labor laws or time zones.

And forget about the age factor. You’re never too old to learn something new. Who cares if you’re nearing 30 or just turned 50? Passion and the drive to learn are what counts. Keep in mind that the tech industry doesn’t care much about your age; your skills are what they’re after.

In the end, it might work for you, it might not. But isn’t life all about taking risks? So venture out, gain a new skill and let uncertainty be your guide. If it doesn’t work out, you’ll have an extra skill in your portfolio, and who knows when it might come in handy?

An iPhone 6 would certainly be a viable option for a work phone, depending on what kind of work you’re doing. If you merely require basic functions like calls, emails, and maybe some light app usage, it will serve just fine. However, if you’re seeking something more intensive like modern productivity or graphic-heavy applications, the iPhone 6 might fall behind due to outdated hardware. Also, if you’re considering video conferencing, newer phones have better camera quality.

Remember to purge it of any personal data and ensure it’s updated to the most recent operating system it can handle. This is to stay relevant with security measures and app compatibility. Battery life can also be an issue with older phones, so keep that in mind too.

Ultimately, it’s down to your requirements. Sure, it’s not the latest and greatest, but as long as it gets the job done for your works, that’s all you need.
