Perhaps you should try some spelling variations:
exertion processing » execution processing (Expand search), extrusion processing (Expand search), emotion processing (Expand search)
decrease exertion » decrease prevention (Expand search), decreases exercise (Expand search), decrease migration (Expand search)
that decrease » that increase (Expand search), that increases (Expand search), not decrease (Expand search)
decrease risk » decreased risk (Expand search), increase risk (Expand search), decrease in (Expand search)
risk decrease » risk decreases (Expand search), risk increase (Expand search), break decrease (Expand search)
decrees that » devices that (Expand search), trees that (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrees that decrease exertion processing ) OR ( decrease risk decrease _ decrease ))~.
