I would expect an old person to be bundled up more than the average person. In fact, during the summer of 1995 in the Chicago area they found old people who had died from the EXTREME heat wave dead in their homes; many with the windows shut and their sweaters on!
As people age, their circulation gets poorer, thus making everything feel colder. So, they bundle up more. That's why you see older folks wearing sweaters etc., when younger folks are in T-shirts.
Odd as this may sound, some people (old and young) like to get the slush off of their driveways, sidewalks et. al., to prevent it from freezing and raising the chance of someone slipping and cracking their head on the pavement.
Also, there is a serious disadvantage older people find when they do heavy snow shoveling - they frequently drop dead!
This is no slip-up.
Is this the part where the cop is interviewing the bar owner? They are both bundled up as if it's sub-zero. If you look, there is water in the gutter. Which would mean that the temp is at least 32 degrees. Certainly balmy weather for northerners.
