Static electricity - WOW

I guess I have a static electricity problem. While cutting a model boat
stand on my router I was using a dust collector . I was holding the
hose by hand. Something touched something else and both I and my
computer got a jolt of static electricity. Has anyone else run into
this? Cures???

I am assuming I need to ground the router which is aluminum on a wood
stand. Do I need to somehow ground the plastic hose on the dust
collector?

Any suggestions, insight, etc. appreciated!!!!!!!!!!!
