I was also jealous of the ppl who lived super unhealthily and never seemed to have issues (well it'll catch up to you over the years but yeah), tho even tho i don't have a high temp (well, not that we keep thermometers in the house) i feel like my colds last at least a week rather than going out the next day or so lol, maybe some ppl have higher immunity if not otc medicine being super strong or so
