Interesting Facts about Breathing!

Breath in
78% Nitrogen
21% Oxygen
1% Argon
0.04% Carbon Dioxide

+ Helium, Water etc.

Breath out
78% Nitrogen
15-18% Oxygen
4-5% Carbon Dioxide
1% Argon

Carbon Dioxide comes from oxidation of glucose (formed from the food we eat)

Trees and plants (alive and dead) give off Carbon Dioxide.

Death Zone

 

Some climbers call heights over 8000 metres, “The Death Zone”. Above this altitude it is difficult to sleep and impossible to eat enough to maintain body weight. No one can survive at this extreme height for more than a few days.

There are only 14 mountains that reach this height, all in Pakistan and Nepal.

They are:

Mountain Height (metres) Height (feet)
Everest 8,848 29,029
K2 8,611 28,521
Kangchenjunga 8,586 28,169
Lhotse 8,516 27,940
Makalu 8,463 27,776
Cho Oyu 8,201 26,906
Dhaulagiri 8,167 26,794
Manaslu 8,163 26,781
Nanga Parbat 8,126 26,660
Annapurna 8,091 26,545
Gasherbrum I 8,068 26,470
Broad Peek 8,047 26,400
Gasherbrum II 8,035 26,360

The Steepest Street in the World

 


Dunedin, in New Zealand, claims to have the world's steepest paved road. However some people challenge Baldwin Street's slope and say mapping error has given it a gradient of 1 in 2.66, or 38%. However, it is almost impossible to ride a bike up or down it. Many of the stiffest road climbs for cyclists are on the Austrian side of the Dolomites (Halltall rises to 1482m in 7km at an average of 14%, its steepest stretch being 32%).

In France from the top of the legendary 1909m Mont Ventoux, there's around 1500m of descent in 21km averaging 7.5%; Iseran's 2770m peak offers 37km of descent and Alpe d'Huez has 21 hairpins.

San Francisco in the USA has some seriousoly steep streets. Take Lombard Street, a short streetcar ride from Fisherman's Wharf. This tourist photostop appeared for years in the Guinness Book of Records under its 'steepest street' entry, despite not even being the steepest street in San Francisco. At 1 in 5.5, or 18%, it's a mere slope compared to neighbouring Filbert St, San Francisco's actual steepest at 1 in 3.2, or 31.5% (22nd St is also 31.5%).

So it looks like Baldwin Street (pictured) may be the steepest after all.
