:) I suppose it would be hard using the space bar w/o the use of one. However I just noticed that I only use my right thumb most of the time. Wait, I do use my left also. Finding this out as I'm typing. Boy, I am ate up!
Note to self: Do not wear open toe sandals when walking about the he-man store with lumber cart loaded with heavy load. Anciallary note: Move feet when performing he-man macho act of yanking lumber cart sideways to make way for elderly woman in wheelchair. Epilogue: Failure to observe the above can result in injury involving ripping toenail from nailbed of large toe, fracturing toe, and culling a large hunk of meat from end of toe.
I admit: I was obliviously macho when performing heroic and manly act of deadlifting cart to yank it sideways, instead of gingerly rolling it along a few more feet.
