In this world, there are reptilean demi-humans (like lizardmen and lamia) which are appearance wise half-human half-reptile, they live in coexistence with humans and other types of demi-humans. These reptileans are poikilothermics (cold-blooded), so in theory they would be vulnerable to cold temperatures and usually seek warm places if possible.
Knowing that these half-human half-reptiles monsters (essentially humans with reptile traces and characteristcs), how could some characteristcs of the reptiles, like being cold-blooded, translate to daily life?
For example: would a reptilean demi-human student have distance education during winters for example? Or maybe heaters being used with more frequency?
How could cold climates affect them in general? Could it be lethal or dangerous to be in cold weather? Or maybe just affect their reflexes and/or disposition? Generate a tendency to hibernate (or brumate)?
