I was watching this fascinating clip on youtube (nice music), and I was curious about the greasy stuff (lanolin?) being applied by the gentleman, apparently to select locations on his body.
Assuming he didn't spread it later, are these locations more sensitive to heat loss, or is he also addressing other issues like friction?
Thanks.
