How many people does it take to change a light bulb if one of them is me?

I am wondering if I should call my elderly neighbor the retired cop over to hold the chair while I try to change the ceiling lightbulb. I'm not sure it would actually help. Just because someone else is here does not mean I will be less likely to get dizzy or lose my balance and fall off the chair, and I'd feel terrible if I squashed and injured him if I fell. These are not the things I though I'd be concerned about in my mid thirties.  Sigh.
