Lifetime of Trousers & shoes 長命褲與長命鞋

I am short and have difficult to find right size of clothes in the UK. So, I buy my clothes almost in HK rather than in the UK. M&S is my favourite brand. They sell all my size there. Ten years ago, I bought a green trouser. I wear it non-stoply during my daily work. I ware it almost anywhere I went to. My friends asked me whether I lacked trousers. I said no. I just loved it, as it was right size, comfortable and causal. After seven years in use, a big hole occurred on back of this trouser. Same story, I had a pair of hiking shoes. it made me feel comfortable. So, I continuly ware it for 2 years. Finally, this shoes had big holes in both shoes caused my heel pain. I am always sad to redundant them. Now, I realise, the lifetime of a trousers is around seven years and of a pair of shoes is around 2 years. OK, how many clothes and shoes do we need? I counted my wardrobe, My clothes which I can wear more than ten years. Why do we need to buy clothes and shoes? For helping the environmental friendly, I stop to buy clothes and shoes many years ago until it is really necessary. I am happy for saving the world resource and being a responsible human. Thanks my Buddha to let me learn the Buddhist theory of cause and effect.
