আমাদের দেশের অধিকাংশ লোকের জন্য বিশুদ্ধ পানীয় জলের সরবরাহের ববস্থা না থাকায় তাহাদের কোন নিরাপত্তা নাই। কারণ তাহাদের অধিকাংশই গ্রামে বাস করে এবং সরাসরি কূপ, পুকুর ও নদী হইতে পানি সংগ্রহ করে। গ্রামবাসীরা জীবাণু সম্পর্কে কিছুই জানে না বলিয়া কলেরা আমাশয় ও অন্যান্য পানিবাহিত রোগের শিকারে পরিণত হয়। যে সকল গ্রামবাসী নদীর তীরে বাস করে তাহারা নদীতে যে কেবল স্নান করে ও ময়রা কাপড়-চোপড় ধোয় তাহাই নহে বরং ইহার মধ্যে সব রকমের আবর্জনা ও ময়লা নিক্ষেপ করে। শেষ পর্যন্ত নদী একটি খোলা নর্দমার মত ক্লেদাক্ত হইয়া উঠে। এই পানি যে সকল রকমের মারাত্মক জীবানুতে পূর্ণ তাহা না জানিয়াই তাহারা এই দূষিত পানি পান করিয়া থাকে। (Translate into English)

I don't want to get old. No one wants to age, but aging is inevitable. Time gives us wrinkles, a bent posture, and fragile bones. It makes us insecure, forgetful, and fearful. The elderly can easily become a burden to the families they once provided for and protected. The children who once vied for their parents, attention are now so consumed with their own affairs that they hardly every visit. For many elderly people, the stench of ammonia in hospital-like atmosphere of a nursing home is worse than death. To some, it signifies than death. To some it signifies loneliness, cruelty and abandonment. With all the turmoil involved in the aging process, it is no wonder that we are becoming a nation of frightened adults, forever searching for that magical youth serum from the elusive fountain of youth.
