A serious hobby - like collecting rare guns and researching their history - is extracurricular academic work and intellectually very stimulating.

Males are genetically more pre-disposed to be affected by compulsive gun collecting disorder (CGCD), while women often suffer from the female version; collecting shoes and hand bags and other knick knacks.
