Don't worry about it. Our society is evolving. As these things become more prevalent, things are done to counteract them.
We're in a transition from industrial to more & more a service based economy. Manufacturing jobs are fewer, & less stable as a result. Service careers are much more fluid by nature, so long term job stability is less of an issue as folks take advantage of better career/gowth opportunities.
There is a health revolution starting. From proper diet to health care & the equitable distribution of cost of healthcare. It's all coming.
