Iowa winters are harsh. This one is especially so, one of the worst in however-many-years. (I try to divert my ears whenever someone is talking about how awful it is outside.) Anyway, Topher has some helpful hints for anyone wanting to warm up:
1) Invest in a poofy coat. This one came from Grandma and Grandpa and we got to test it when the temperature (not the wind chill, mind you) was negative 13 degrees.
2) Stay active. Do some lunges (use nearby furniture for balance if necessary.) Then practice walking.
3) Always keep a blanket on hand. Even if it's lunch time. Sometimes you just don't want to let go of something so soft and warm.
4) Finally, if all else fails, find someone you really love and snuggle up close.
Actually, this one might be better as a first resort rather than a last.
