I wrote a long time ago that cannabis sativa may not be good for your health, and today I see that the University of South Wales, Sydney has published a research paper titled Heavy teenage cannabis use linked with anxiety disorders in late 20s. The article cites a noted relationship between teenage weed use and late-20s anxiety mental disorders:

Teenagers who smoke cannabis weekly or more are twice as likely as non-users to have an anxiety disorder in their late 20s, even if they stop using, a study of 2000 Victorian teenagers has found. [...] [T]he really striking finding say the authors is the persistent association between frequent teenage cannabis use and adult anxiety disorders up to a decade after cannabis use has ceased. The relationship between cannabis use and anxiety disorders was present even after the researchers took into account other possible explanations such as mental health problems in their teens or other drug use in their twenties.

The researchers note that causation has not yet been explained:

Professor Patton, lead investigator of the 2000 stories cohort, said that the findings could be explained by lasting changes to brain function caused by introducing cannabis at a time when the brain is developing rapidly. Equally it could be that the very factors which predispose people to use cannabis early also predispose them to common mental health problems.

The study itself notes a possible positive note:

There were no consistent associations between adolescent cannabis use and depression at age 29 years.

You can read the research paper (PDF) for yourself to get the dirty details.

My calves burned with a low throb, incomparable to the pain on the track, as I watched the muddy water–brown–spiral down the bathtub drain. Washing the mud off after Tough Mudder Tri-State 2011, 12 miles of mud, obstacles, and freezing water, was the real end of the race, the delineating point at which I could return to my regular home, body, and life.

The weather in Jersey when we ran was in the mid-50s, with a cold wind blowing hard. We kicked off around 11:30 and crossed the finish line at 3:15, after stopping for 30 minutes to drop of two injured teammates at the first-aid station at mile 6. Volunteers told us that at least four ankles had been broken already at the monkeybars obstacle, and we saw others who fell wrong mid course or fell to hypothermia being carted away by ambulances that were standing by. Signs along the way taunted our determination with “you signed your death waiver already” and “you just completed a Warrior Dash” (at mile 4).

The Course

The course map tells part of the story, but running the track is another experience entirely. After running and climbing through a rope obstacle (easy!) you are asked to take the Chernobyl Plunge a dive into a pool of icey water with food colouring added (you get a choice of green/red/purple), submersion under barbed wire, and them up the other side of the pool where you clamber out. The water is chest-deep, refrigerated, and has ice cubes literally floating in it:

See that ice? SEE IT?

This sets the stage for your upcoming hypothermia. After shimmying across ropes strung across a lake, then climbing over 9 foot walls–teamwork required–you hit another obstacle, a 20 drop into the cold lakewater, followed by a couple hundred foot swim to the other side. You get out cold, wet, with the sharp winding blowing through you. But what’s coming is why you joined Tough Mudder–THE MUD!!!

I haven’t ever jumped from this high before

They call it “the mile of mud”, where you slog through waist/chest high slippery mud. After that, there’s crawling under barbed wire through mud, crawling through muddy pipes, crawling under a heavy net in mud, slogging up and down a dirtbike track, then sliding down a mud mountain!

Some of my favourite obstacles were the hay piles you climbed over (reminds me of Alberta’s rural landscape), and the balance beam over frigid water. I was warm and dry from the sun by this time and was extremely motivated to avoid falling in. My teammate did, but I made it across without an unnecessary dousing! The fire obstacle was running between two sets of fires, and through the smoke, but not actually overtop of any fire, so I thought that was a bit lame. I also didn’t get electric shocked!

Tough Mudder Tips

• Dress for the event. Running leggings (like these CW-Xs) help immensely with the cold and sliding through mud. Wear a long sleeved shirt that doesn’t soak up moisture–not cotton. Bare skin is a no-no.
• It wouldn’t hurt to wear a swimming cap, but goggles are useless in mud
• Take the obstacles slowly and carefully, as your shoes are heavy with mud and slippery. You don’t want a nasty fall or scrape.
• Help others on course! They will help you too!

Cameraderie

One thing that struck me was the team spirit present. While people are there to push themselves hard, it’s not an individual event, it’s more of a team sport. At every obstacle, other racers are there helping people up the high walls, pulling them up the halfpipe, or lending a hand at the end of the inclined submerged tunnels:

I enjoyed helping others through some of the harder obstacles as much as I enjoyed completing the race on my own. The feeling is completely different than running a competitive pure-running race, for time, where everyone is only out for themselves. Tough Mudder brings out humanity’s cooperative and compassionate nature. I heard nothing but encourgement shouted out to myself and others the whole track, tips and muscle freely given.

Tough Mudder and Beyond

Tough Mudder will mark you for life. Even after you’ve washed off the superficial mud, cleaned and healed your scrapes and bruises, warmed up and changed into new clothes, even running other races, you won’t be able to forget that you once ran 12 miles on a cold windy day fearing the worst and made it. Now that I’ve run Tough Mudder, I’m no longer afraid to take the next challenge. I can do anything!

This bug bite is odd–I don’t know where it came from. It is small, less than 2cm of swelling, slightly itchy, and features a square-shaped series of four symmetrical bite marks. What particular bug or arthropod did, I do not know. My home appears to be free of most insects, and there are no bed bugs or spider webs around. I could have also picked up the bite while hiking outdoors in Alberta’s Elk Island National park in Canada, or roaming outside in NYC. My suspicion is that it is some kind of small bite.

Picture of the bite, in context. Bit marks have been increased in contrast so they would show up–they are quiet faint after the third day

Closeup of the bite

In any case, there is no pus, tissue decay, ringing, hives, blisters or lesions. So whatever bug/spider bit me, it is a nuisance and little more. I hope that a commenter who is also an entomologist, MD, or enthusiast can let me know what this might be!
