Actually, I find it absolutely hilarious how many people are offended because the term fat, tubby, lard ass, jumbo are being used in this term to define obese individuals.
Why do I find this funny?
Because I was a lazy, fat assed smoker who treated those people who were fit like ****. I wasn't alone, as a matter fact, I was not even in the minority. I fought like a mother ****er to go from 300 down to my 170 lbs. and you know what, in general, I've found that most of the people I was accustom to making fun of you with are just as capable of losing the weight, and the coveted title of gutus maximus.
I quit smoking.
I quit eating like a pig.
I started riding.
I started running.
Oddly, I didn't see anybody making fun of them for walking, the joke is that they're LARGE, OBESE individuals making up their own rules when clearly, they're not holding any license to exercise anymoreso than the OP who merely was saying they put him and his wife in danger.
Stop chastizing and start realizing that everybody gets to sit in the barrel every now and then.
