Personal heating solutions

I'm what my mum always called "nesh" - a Yorkshire term (I think), which Wikipedia defines as "unusually susceptible to cold weather", so in the colder months I'm always on the lookout for solutions that make my life a little easier (i.e. warmer), whether that's in the office (which can be a little colder than I find ideal), when driving, and when out and about.

For driving, Andy's last car had heated seats and - joy of joys - a heated steering wheel.  Pure bliss.  My own little cars, and Andy's current one have had no such luxuries, so I needed other solutions.
