Who me?
As far as condiments, I use a lot of Franks Redhot Sauce.  I don't, as the commercials say, put that shit on everything, but I put it on most kinds of meat in most kinds of meat eating situations.  I'd guess I have it with dinner an average of 5.8 days a week.  I have some mustard (plain old French's yellow) for various sandwiches/burgers/sausages.  I usually put Miracle Whip on homemade subs which I have about once a week.  And I have some ketchup in there.  My ketchup use is sporadic.  A bottle of ketchup can last me a long time.  
Lemme look . . . I have some plum sauce.  I went through a serious chicken balls eating phase not long ago so there's gotta be plum sauce.  I don't know if vinegar counts but I have that.  I love vinegar on french fries which I cook up once in awhile.
I do not own a spice rack, no.  My "go to" spice would have to be garlic.  Much like the Franks sauce, I put it on meat - and I eat meat every day.  Well actually pepper even more than that.  Is pepper considered a spice?  I have pepper on everything I have garlic on - and much more.  Tomatoes, potatoes, salad, soup, any kind of sandwich.  Pepper is such a routine thing I hardly think of it as a spice but I guess it is so it would be #1.  
I don't know how old my oldest underpants are.  Not old.  As soon as they get ratty, I just toss them.  I really don't even have a guess how long that takes but I cycle the underpants pretty effectively.  
I find it weird that underpants is plural.  Why is underpants a pair?  There is just one thing there.  Why is it they?
Anyhoo . . . 
I do have a few scented candles around here.  One is vanilla and was given to me at a wedding.  I have 2 or 3 cinnamon candles and I can't rightly recall their origin.  They have just been sitting in a cupboard for probably over 10 years.  Seems that I never burn candles.
Couple more questions there.  I will get back to them.
