Doing something crazy

My ex-boss wrote - about his desire to rekindle his passion for cycling although he is about 20 years older now and is also about 1.3 times in size now.

My comment to him was ...I was telling my sis recently..i am such a hopeless being. I realised long ago that i have not really done 'anythg' in my life AND to make it worse..I am not doing anything to rectify it...e.g. I don't really kow how to swim, i daren't dive, i don't rock climb, I can't really cycle, i don't travel much...i have not back paked before...and the list goes on and on..

Well..It's all about doing somethng crazy isn't it...does going for Tai Chi count?
