That isn't the right question. The right question is can you do it, and will it pay enough to provide "a good life" (whatever that means to you). If you love [whatever] more power, that is the best case. However don't lose track of the fact that in the end no matter what job you pick there will be times when you have to do something you hate (not something unethical where you should quit, just something you hate), but you need to do something to be a good citizen.
If your kids already have a good career picked out I encourage a secondary study in some hobby thing. Go ahead and sing in the choir even though as an engineer it is a waste of time - that is fun and that is good (there are thousands of other fun things). Just don't lose sight that the goal is a good life and this will include things you don't want to do but have to anyway.
