🍬 甜 = sweet + 头 = head/end; the sweet end you get, a benefit or perk
甜 — tongue 舌 + sweet 甘
甜 is a compound ideograph combining 舌 (tongue) and 甘 (sweet, itself a pictograph of something held in the mouth). The tongue tasting something sweet conveys the meaning 'sweet' or 'pleasant'. It largely replaced 甘 as the everyday word for sweet taste.
头 — 页 (head/page) + 豆 (bean, phonetic)
The traditional form 頭 combines 頁 (xié), meaning 'head', with 豆 (dòu) as the phonetic component. 頁 itself originally depicted a person with an emphasized head. The simplified form 头 is a modern shorthand that replaces 豆+頁 with a simpler shape while keeping the same meaning of 'head' or 'top'.
