You guys that gotta break out the thermal underwear for 0F temps, try to stay warm. 
You got that right. In fact after looking at the forecast and today at 32 is the warm day, I'm headed out to prune the fruit orchard.
And for sure I will have a set of sweats under the overalls to keep warm. I'm not a hunter so no fancy underarmor gear. Shouldn't take me more than an hour or two.
but it does mean using a large fairly heavy ladder. What I'd really like is for someone to lift me up in my man bucket with the tractor but doing it the old fashioned way is
no strain for another couple of years until the trees become full sized. Then using that bucket will be a good solution for me for pruning, with a helper.
I was going to trim my beard yesterday as I keep it fairly short and thought with the temps this coming week, let it grow longer.
Just a marvelous insulator for outside. Like your own little portable face fleece...
Mine will come off in February when it starts getting warm here again.
L4N, beards there must be very common. Takes some maintenance, like pruning a shrub.
