Yes, stress absolutely physically manifests itself now with minimal effort, it can be noticeable within minutes of high stress situations.

My problem is that it's almost impossible to create a low/no stress environment right now.
I'm the sole source of income, work multiple jobs, have two kids in college (with two more at home), financial strain, and so on. I highly value things that help destress or minimize stress for me; I would dearly love to just stop and rest until my body recovers, but it's not a feasible option right now as we would lose our house and such.
