1. Half-time in a football (soccer) match 15 min

   The break exists partly thanks to early English schools with different rules — teams switched codes at the interval when playing each other.

2. A standard university lecture 50 min

   Attention research suggests student focus starts lapsing after 10-15 minutes — which is roughly when most lecturers are just warming up.

3. Yuri Gagarin's entire Vostok 1 spaceflight 108 min

   The first human spaceflight was a single orbit — and Gagarin ejected and parachuted down separately from his capsule, landing in a potato field.

   Chicks start cheeping to their mother through the shell a day or two before hatching — and she clucks back to encourage them out.

5. The Edinburgh Festival Fringe 25 days

   The world's largest arts festival stages over 3,000 shows — by ticket sales it trails only the Olympics and the football World Cup.

6. The era of the Crusades, from the first to the fall of Acre 194.9 years
