| Are some people born clever and others
born stupid Or is intelligence developed by our environment and our experience
Strangely enough, the answer to these questions is yes. To some extent, our
intelligence is given us at birth. On the other hand, a child who lives in
boring environment will develop his intelligence less than one who lives in rich
and varied surroundings. Thus the limits of a person’s intelligence are fixed at
birth, whether or, not he reaches those limits will depend on his environment.

入住后不久别墅屋顶果然漏水，甲要求乙进行维修，乙认为在订立合同时已对漏水问题提前作了告知，甲当时并无异议，仍同意承租，故现在乙不应承担维修义务。于是，甲自购了一批瓦片，找到朋友开的丁装修公司免费维修。丁公司派工人更换了漏水的旧瓦片，同时按照甲的意思对别墅进行了较大装修。更换瓦片大约花了10天时间，装修则用了一个月，乙不知情。更换瓦片时，一名工人不慎摔伤，花去医药费数千元。
2005年6月，由于新换瓦片质量问题，别墅屋顶出现大面积漏水，造成甲一万余元财产损失。
2006年4月，甲遇车祸去世，丙回娘家居住。半年后丙返回别墅，发现戊已占用别墅。原来，2004年12月甲曾向戊借款10万元，并亲笔写了借条，借条中承诺在不能还款时该别墅由戊使用。在戊向乙出示了甲的亲笔承诺后，乙同意戊使用该别墅，将房屋的备用钥匙交付于戊。
问题：
甲丁之间存有什么法律关系？其内容和适用规则如何？摔伤工人的医药费用、损失应如何处理？理由是什么？
