Buying hats may well prove troublesome, but having a huge head also brings a key advantage - it means you're less likely to suffer mental decline in old age.
Catherine Gale (MRC Environmental Epidemiology Unit, University of Southampton) and colleagues recruited 215 men and women aged 66-75 years, measured their head circumference (itself an indicator of brain size) and gave them two sets of intelligence tests - first at the head-measuring session and then again, three and half years later. Old records also detailed the participants' head circumference at birth.
People with bigger heads scored more highly on the intelligence tests, and were less likely to show mental decline as indicated by a lower score at the second testing session relative to the first. In fact, the bottom quartile (25 per cent) of the sample for head size were five times more likely to exhibit mental decline than the quartile with the biggest heads.
Head circumference at birth, by contrast, had no relationship with intelligence or mental decline. This has important implications, because as the authors explained, it suggests "brain development during infancy and early childhood is more important than foetal growth in determining how well cognitive abilities are preserved in old age".

1. Sapa2 ada baby tu, jangan biarkan baby tido dengan kepala yang statik lebih sejam. Nanti beban kepala akan mengecilkan saiz tengkorak dan seterusnya menghalang perkembangan saiz otak. Alih2kan sket kepala tu.
2. Jangan tiru omputeh plak. Dengan menidurkan baby mereka secara meniarap bagi mendapatkan pembesaran saiz tengkorak yang bebas. Ianya meningkatkan risiko mati mengejut. Tidur tiarap dalam setengah ok kot (tanpa ujikaji.)
Gua rasa, Hadi Awang dulu, masa kekecik kaki buai tu. Bila nangis, bapak dia buai. Lepas makan, buai. Sakit, buai. Bosan, buai. Tu yang dia khayal dalam arus perebutan pengaruh wadah undi demi Islamic State tuh.
Siyes ni. Gua pesan kat diri sendiri, dan lu orang semua. Sudah2la menggunakan buai bagi jalan penyelesaian kepada situasi anak kecil anda.
