Wife just popped by, asked me not to ride my MB to work (.75 mile, one-way) 'cause of the 151 number media's put on current air quality here, now that yesterday's front has pushed out the HOT humid air we've suffered with for weeks for much cooler (but maybe toxic?) air.



So just how bad is too bad for us to ride? Anything meaningful for age groups?

I'm mid-70's, commuting doesn't get me breathing hard but I do tend to huff & puff when I'm riding for recreation, which I fully expect to do tomorrow when I have more time before my afternoon's second half-day-at-work this week.
