6. 個人經驗與觀點
「你以為自己仲好後生？計下你活咗幾多日先講嘢。18 歲 = 6,570 日，30 歲 = 10,950 日，40 歲 = 14,600 日。人嘅一生大約得 30,000 日——你用完咗幾多？呢個工具唔只係計數，佢係一面鏡。你望住個數字嘅時候，唔係諗『我幾多歲』，而係諗『我仲有幾多日』。而呢個 question，會改變你點樣過聽日。」

6. Personal Insights & Expert Advice
"Think you're still young? Calculate how many days you've been alive first. 18 years = 6,570 days, 30 years = 10,950 days, 40 years = 14,600 days. A human life is about 30,000 days—how many have you used? This tool isn't just about counting. It's a mirror. When you look at that number, you're not thinking 'how old am I'—you're thinking 'how many days do I have left'. And that question changes how you live tomorrow."
