We present the CDF results using 1.0 fb-1 of data on the mixing frequency measurement in the Bs system and the lifetime measurements of several B hadrons. We obtain Δ ms=17.77 +- 0.1 +- 0.07 ps-1 and cτ(Λb)=473.8 +- 23.1 +- 3.5 μ m. The later one is more than 3 sigma above the world average, but in reasonable agreement with HQE calculations.
